# Invoket

> The checks AI agents run before they act — verify bank accounts before paying, phone numbers before messaging, laws in force before advising, weather before deciding, vehicles before buying. Computed from official sources (bank registries, OFAC/EU/UN lists, LEGI/EUR-Lex, ERA5/GFS, NHTSA vPIC), with provenance in every response. Pay per call in USDC, no account, no API key — you only pay for answers. The live catalog is served by the gateway.

An empty list is a successful answer. No account, no key, pay per call through x402.
- [GET /vehicle/critair](https://invoket.com/docs/api/vehicle-critair) — Crit'Air class and current low-emission-zone (ZFE) restrictions for a vehicle, computed offline from declared characteristics - fuel plus Euro norm or first-registration date - as a UnifiedResponse. Pure regulatory calculation, no store, no network. An unclassified vehicle is still a successful answer. No account, no key, pay per call through x402.
- [GET /vehicle/co2](https://invoket.com/docs/api/vehicle-co2) — Type-approval CO2 emissions and technical characteristics of a European vehicle - WLTP g/km with its p10/p50/p90 dispersion, fuel, engine capacity, power and mass - read offline from the official EU CO2 monitoring dataset (Regulation (EU) 2019/631), keyed by type-approval number or by make, model and year, every answer stating the precision it was matched at, as a UnifiedResponse.

- [GET /vehicle/report](https://invoket.com/docs/api/vehicle-report) — A composite vehicle report for one VIN in a single x402 settlement - VIN decode (always present) plus candidate recall campaigns, type-approval CO2, the French registration tax it would cost and, when declared characteristics are supplied, a Crit'Air class, each block carrying its own provenance, returned as a UnifiedResponse. A partial report is a successful, billed answer. No account, no key, pay per call through x402.
- [POST /invoice/read](https://invoket.com/docs/api/invoice-read) — Faithful structured extraction of a European electronic invoice (Factur-X/ZUGFeRD PDF, CII D16B, UBL 2.1) into the EN 16931 semantic model - parties with SIREN/VAT ids, lines, VAT breakdown, totals, payment IBAN, due dates - as a UnifiedResponse. No OCR guesswork, no account, no key, pay per call through x402.
- [POST /invoice/validate](https://invoket.com/docs/api/invoice-validate) — Deterministic EN 16931 conformance verdict on a European electronic invoice (Factur-X/ZUGFeRD PDF, CII D16B, UBL 2.1) in four reported layers - XSD, business rules with official BR-xx ids and observed/expected values, Factur-X profile conformance, identifier plausibility - plus optional national/network CIUS rule packs via ?ruleset=xrechnung (German BR-DE, faithful to KoSIT) or peppol (Peppol BIS Billing 3.0, faithful to OpenPeppol). One surface, three markets. Sourced rule ids, no LLM. No account, no key, pay per call through x402.
- [POST /invoice/generate](https://invoket.com/docs/api/invoice-generate) — Generate a CII D16B or UBL 2.1 electronic invoice guaranteed conformant to EN 16931 - and, in UBL, guaranteed conformant to Peppol BIS Billing 3.0 - from a simple business JSON - parties, lines, VAT. Generated-then-validated - every XML served has already passed the four validation layers of /invoice/validate, official BR-xx rule set (plus the PEPPOL-EN16931-R pack for Peppol), pinned CEN and OpenPeppol artefacts. The only x402 generator that guarantees and re-proves Peppol BIS 3.0. Actionable 400 issues, all reported together. No account, no key, pay per call through x402.
- [POST /invoice/generate-pdf](https://invoket.com/docs/api/invoice-generate-pdf) — Generate a complete Factur-X document - a readable PDF/A-3B invoice carrying an embedded CII D16B XML (factur-x.xml) guaranteed conformant to EN 16931 - from the same business JSON as /invoice/generate. Generated-then-validated and re-read - the embedded XML passed the four validation layers and was re-extracted bit-for-bit by our own reader before anything is served. veraPDF-conformant PDF/A-3B, byte-deterministic output. No account, no key, pay per call through x402.
- [POST /invoice/vat-treatment](https://invoket.com/docs/api/invoice-vat-treatment) — Determine the VAT treatment of one cross-border transaction under Directive 2006/112/EC - place of supply, person liable, mechanism (standard, reverse charge, intra-Community exemption, exempt export, out of scope), the standard rate in force at that date, and the exact invoice mentions to print - each sourced article by article, with an honest undetermined for the regimes it does not cover. Returned as a UnifiedResponse. No account, no key, pay per call through x402.
- [POST /invoice/vat-treatment/batch](https://invoket.com/docs/api/invoice-vat-treatment-batch) — Judge a sales ledger in one call - up to 200 transactions, one VAT determination each under Directive 2006/112/EC, one x402 settlement. Same verdicts as the single call (place of supply, person liable, mechanism, rate in force at each date, compulsory invoice mentions), with legal bases and caveats deduplicated and cited by key, a malformed item reported at its position, and a summary counting the five mechanisms. Returned as a UnifiedResponse.

Every tranche carries its reference rate, statutory rate and interest, so the figure can be recomputed by hand. Returned as a UnifiedResponse.

A SIREN known to the Sirene register with no announcement is a paid 200 with an empty list over a stated coverage window; a well-formed SIREN unknown to that register is a 404, not billed - "unknown to the register" is not the same answer as "known, without announcements". No account, no key, pay per call through x402.
- [GET /company/vat](https://invoket.com/docs/api/company-vat) — Live intra-EU VAT number validation against VIES (European Commission) for any member state, plus offline derivation of the French VAT number from a SIREN. Three outcomes - valid, invalid, unverifiable - are all paid 200 answers - the agent pays for a check that ran, not for a "positive" result. An unavailable member state falls back to our last firm verdict on the number, served as cached and dated by its age, or degrades to an honest syntax-only answer - never a 5xx. No account, no key, pay per call through x402.
- [GET /company/peppol](https://invoket.com/docs/api/company-peppol) — Is a company reachable on the Peppol e-invoicing network, under which identifiers and for which document types? Answered offline from the ingested public export of the Peppol directory - a dated photo (coverage.directory_as_of), never a live SMP lookup. "Not registered" is a paid 200 answer (reachable false), never a 404 - the absence is the answer, dated. The one 404 is a well-formed siret= or siren= that does not exist in the Sirene register - unknown is unknown on every route of the service, and it is not billed; participant= is never concerned, it can name any country. The French index returns every identifier a SIREN is known under, including the CTC routing sub-addresses of the 2026 French e-invoicing reform. No account, no key, pay per call through x402.
- [GET /company/lei](https://invoket.com/docs/api/company-lei) — Legal identity of a company anywhere in the world from its LEI, BIC, ISIN, French SIREN or exact name plus country - legal name, jurisdiction, entity and registration status, addresses and mapped market identifiers, served offline from the official GLEIF LEI reference (3.3M+ entities, CC0) as a UnifiedResponse. An ambiguous key returns every candidate, never an arbitrary pick. No account, no key, pay per call through x402.
- [GET /company/ownership](https://invoket.com/docs/api/company-ownership) — Who controls this counterparty - direct parent, ultimate parent, the dated chain between them and the direct subsidiaries, from the GLEIF Level 2 relationships (CC0), served offline as a UnifiedResponse. These are self-declared accounting-consolidation parents, NOT beneficial owners under AML/KYC rules, and Level 2 publishes no ownership percentage. A published non-reporting reason is served as the answer. No account, no key, pay per call through x402.
- [GET /company/report](https://invoket.com/docs/api/company-report) — Complete due diligence on a French company in one paid response, by SIREN - official identity (Sirene), dated legal events (BODACC), live VAT validation (VIES), Peppol e-invoicing reachability and the global GLEIF identity with its ultimate consolidating parent, each block carrying its own provenance, never smoothed under one date. The showcase pre-action counterparty check before you invoice, pay or onboard - no account, no key, no Creditsafe/Pappers subscription. An unknown SIREN is an unbilled 404, never an empty billed report. The summary is mechanically derived facts, not a risk score. Pay per call through x402.
- [POST /certify/batch](https://invoket.com/docs/api/certify-batch) — Certify a file of French counterparties in one call - up to 200 SIREN or SIRET lines, one sourced verdict per line from the INSEE Sirene register and the BODACC gazette, the name you hold compared to the one the register publishes, and an Ed25519-signed Merkle root that lets the buyer of the file verify any single line offline, with a public verifier and no dependency on us.
- [GET /medication/resolve](https://invoket.com/docs/api/medication-resolve) — Official identity card of a medication from its French CIS code, US NDC, exact name (+country) or INN/DCI substance - marketing-authorization status, active substances normalized to the INN, presentations with public price and reimbursement rate, and generic group, served offline from the monthly French BDPM register and the US openFDA/RxNorm datasets as a UnifiedResponse.

Served offline from the monthly French BDPM register as a UnifiedResponse. No account, no key, pay per call through x402.
- [GET /medication/availability](https://invoket.com/docs/api/medication-availability) — Check a French medication's market availability from its BDPM CIS code or an INN/DCI substance - the official ANSM shortage reports (rupture, risk of shortage, tension, return to market, discontinuation) relayed exactly as published, with dates, medical domain and the official ANSM report URL. Honest by design: ANSM only records reported shortages, so the absence of a report is never a stock guarantee. Served offline from a data.ANSM snapshot as a UnifiedResponse. No account, no key, pay per call through x402.
- [POST /medication/interactions](https://invoket.com/docs/api/medication-interactions) — Check drug-drug interactions between 2+ medications against the official French ANSM interactions thesaurus - the authoritative constraint level, management and mechanism relayed exactly as the ANSM wrote them. Post CIS codes, US NDCs, INN/DCI substances or ANSM classes; US products join the French thesaurus through the INN substance bridge. Honest by design: 'no interaction' is asserted only for pairs actually compared, everything else falls into an explicit coverage block - never a fake all-clear. Served offline from an ANSM snapshot as a UnifiedResponse. No account, no key, pay per call through x402.
- [GET /medication/report](https://invoket.com/docs/api/medication-report) — Everything an agent needs to know about a medication before acting on a prescription or an order, in one paid call, by French CIS code or US NDC - official identity and price (BDPM), generic group (BDPM), reported shortages (data.ANSM) and the drug-drug interactions of the ANSM thesaurus between the subject and an optional list of co-medications. Four sections, each carrying its own source and date - never smoothed under one date. The showcase of the Medication family: the four unit endpoints consolidated into a single settlement. Sourced, dated facts, never a clinical opinion. Served offline as a UnifiedResponse. No account, no key, pay per call through x402.
- [GET /label/chem/classify](https://invoket.com/docs/api/label-chem-classify) — Harmonised CLP classification and labelling of a substance from its CAS number, EC number or exact Annex VI name - hazard classes with H-statements, GHS pictograms, signal word and concentration limits, versioned by ATP (in force at the queried date, plus any upcoming change) with the CELEX number and EUR-Lex link of the act each entry version comes from, served offline from the ECHA Annex VI (CLP) as a UnifiedResponse.

- [POST /label/claims/check](https://invoket.com/docs/api/label-claims-check) — Check a proposed food-label wording against the EU Register of nutrition and health claims (Regulation (EC) 1924/2006) - is the claim authorised (exact legal wording and conditions of use), non-authorised (full official rejection reason and EFSA opinion), a partial fragment, or absent from the register. Strict, never fuzzy matching served offline as a UnifiedResponse. No account, no key, pay per call through x402.

- [POST /preflight/invoice-payment](https://api.invoket.com/preflight/invoice-payment) — Before your agent pays a supplier invoice: send the invoice file itself (Factur-X PDF, CII or UBL XML) and get one verdict - pay, hold, stop, insufficient_coverage - over the document's EN 16931 compliance, the supplier in the INSEE Sirene and BODACC registers, live EU VAT (VIES), sanctions screening of the party actually credited, VAT consistency and the statutory due date. Every reason names the block and the source it comes from. ($0.25, free trial: 1 free call per day per payer address)
- [GET /preflight/payment](https://api.invoket.com/preflight/payment) — Run every check on a bank transfer before your agent executes it, in one call: IBAN validity, bank and BIC from national registries, SEPA scheme reachability from the EPC register, sanctions screening of the bank and of its jurisdiction (OFAC, EU, UN, FATF), and screening of the beneficiary name against the OFAC, EU and UN designation lists.

Law-in-force checks backed by LEGI (Légifrance), EUR-Lex and the official public-holiday calendars — every response carries its provenance.

- [GET /legal/article](https://api.invoket.com/legal/article) — Before your agent cites, advises on or drafts against a French law: check the article is in force at a given date — consolidated text, status (in force / repealed / deferred) and validity dates, from the official Légifrance LEGI dataset.

Holiday calendars for 10 countries: France from the official State dataset, the nine others from a community reference dataset, and every answer says which authority it used. The regime is required and never inferred from the legal matter. ($0.01, free trial: 1 free call per day per payer address)
- [GET /legal/diff](https://api.invoket.com/legal/diff) — Before your agent updates a contract clause or a compliance rule that depends on a law: see exactly what changed in a French or EU article between two dates — resolves the version in force at each date, from the official LEGI and EUR-Lex datasets, and returns a word-level diff plus a git-style unified patch with both versions' metadata.

- [POST /legal/history/batch](https://api.invoket.com/legal/history/batch) — Before your agent re-certifies a legal knowledge base or monitors a portfolio of citations: the version timeline (status and validity dates) of up to 100 French or EU article references in one call, from the official LEGI and EUR-Lex datasets, to detect which references changed and when. Covers 12 major French codes and statutes and key EU acts (GDPR, DSA, AI Act, MiCA and more). ($0.005 + $0.005/ref)
- [GET /legal/transposition](https://api.invoket.com/legal/transposition) — Before your agent relies on an EU directive producing effects in a Member State: in force, applicable and transposed are three different things. This returns the national implementing measures a Member State has notified to the European Commission for an EU act — each measure with its national act type, title, national reference, publication and notification dates — plus the published transposition deadline and how many days the first notification came after it (positive means late). Ask for one country, or omit it for a one-line verdict on each of the 30 EEA States. What is served is a register of notifications, never an assessment of conformity. ($0.01, free trial: 1 free call per day per payer address)

### Before your agent plans or insures

Weather and climate checks backed by Copernicus ERA5, NOAA GFS/GEFS and the WMO 1991-2020 normals — every response carries its provenance.

- [GET /climate/anomaly](https://api.invoket.com/climate/anomaly) — Before your agent verifies a 'hotter than normal' claim, reports climate exposure or settles an anomaly-based trigger: how far observed temperature, precipitation and wind departed from the WMO 1991-2020 climatological normal, for any GPS point or city over a date range within the ingested Copernicus ERA5 window (rolling 30 years for temperature and precipitation, rolling ~5 years for wind). ($0.01, free trial: 1 free call per day per payer address)
- [GET /climate/degree-days](https://api.invoket.com/climate/degree-days) — Before your agent sizes heating or cooling demand, settles an energy contract or models crop growth: heating, cooling and growing degree-days (HDD/CDD/GDD) for any GPS point or city over a date range, computed from Copernicus ERA5 daily mean temperature (rolling 30-year window) with the NWS/EIA/WMO mean-temperature method. ($0.01, free trial: 1 free call per day per payer address)
- [GET /climate/indices](https://api.invoket.com/climate/indices) — Before your agent prices or settles a parametric-insurance trigger, or screens weather risk for agriculture and construction: climate-event indices for any GPS point or city over a date range — frost and summer days, tropical nights, dry spells, heavy-rain days, max one-day rainfall, total precipitation and peak gust — ETCCDI/Climdex definitions on true daily Tmin/Tmax from the Copernicus ERA5 reanalysis (precipitation-based indices: rolling 30-year window; Tmin/Tmax- and gust-based indices: rolling ~5-year window). ($0.01, free trial: 1 free call per day per payer address)
- [GET /climate/point](https://api.invoket.com/climate/point) — Before your agent verifies a weather-dependent claim, backtests a parametric trigger or checks what conditions a site or shipment faced: daily 2 m temperature, total precipitation and 10 m wind at any GPS point or city for a past date, from the Copernicus ERA5 reanalysis — temperature and precipitation cover a rolling 30-year window, wind a rolling ~5-year window — with the served grid cell and a coverage flag. ($0.01, free trial: 1 free call per day per payer address)
- [POST /climate/point/batch](https://api.invoket.com/climate/point/batch) — Before your agent backtests parametric triggers over a site portfolio, verifies claims across parcels or scores weather exposure for an asset fleet: daily 2 m temperature, total precipitation and 10 m wind for up to 500 point/date queries in one call, from the Copernicus ERA5 reanalysis (temperature and precipitation: rolling 30-year window; wind: rolling ~5-year window). Each query takes lat+lon or a city name; an uncovered item is flagged via per-item coverage instead of failing the batch. ($0.005 + $0.005/query)
- [GET /climate/return-period](https://api.invoket.com/climate/return-period) — Before your agent underwrites, reinsures or stress-tests a climate exposure: rank a target year's season against 30 years of a location's climate history (Copernicus ERA5 reanalysis, WMO-standard climatological period) — percentile, empirical return period and sample size, for any GPS point or city. Temperature and precipitation cover a rolling 30-year window; every verdict reports its actual sample size via sample_years and coverage. ($0.01, free trial: 1 free call per day per payer address)
- [GET /weather/forecast](https://api.invoket.com/weather/forecast) — Before your agent schedules a delivery, plans outdoor work or hedges short-term weather exposure: a point forecast of 2 m temperature, precipitation and 10 m wind — plus opt-in convective, humidity, cloud and snow variables — for any GPS point or city. Deterministic NOAA GFS at 0.25 deg to 16 days (384 h), NOAA GEFS ensemble mean at 0.5 deg to 35 days (840 h) — beyond 16 days the value is an ensemble mean with smoothed extremes: trend, not threshold triggers. The lead selector is optional (omitted, the forecast defaults to the current analysis time) and the response names the model that served it and the exact forecast step. ($0.01, free trial: 1 free call per day per payer address)
- [POST /weather/forecast/batch](https://api.invoket.com/weather/forecast/batch) — Before your agent plans across a whole network — fleet routing, multi-site operations, portfolio hedging: 2 m temperature, precipitation and 10 m wind forecasts for up to 500 point + lead-time queries in one call, from the deterministic NOAA GFS run (~16 days). Each query takes lat+lon or a city name plus an optional lead selector (omitted, it defaults to the current analysis time); an uncovered item is flagged via per-item coverage instead of failing the batch. ($0.005 + $0.005/query)
- [GET /weather/forecast/daily](https://api.invoket.com/weather/forecast/daily) — Before your agent plans a multi-day operation — logistics, construction, an event, crop work: a day-by-day forecast for any GPS point or city, with daily minimum and maximum 2 m temperature, total precipitation and peak 10 m wind per UTC calendar day, from today to the end of the NOAA GFS window (~16 days), extendable to 35 days on the NOAA GEFS ensemble mean — those extra days are an average of ~30 members, so their extremes are smoothed: trend, not threshold triggers. Each day names the model that served it and carries a coverage flag. ($0.01, free trial: 1 free call per day per payer address)
- [GET /weather/forecast/exceedance](https://api.invoket.com/weather/forecast/exceedance) — Before your agent commits to a rain-or-shine decision two to five weeks out — a parametric payout, a shipping window, a harvest or concrete slot: how many NOAA GEFS ensemble members cross your threshold on each day of the ensemble tail. Ask 'at least 30 mm of rain in a day', 'wind at or above 15 m/s' or 'a day at or below 0 deg C' for any GPS point or city, and get one counted fraction per UTC calendar day with the member count behind it. Ask days= (up to 20) for the whole tail. This is what the ensemble MEAN served by GET /weather/forecast cannot answer: averaging the members smooths extremes away, so a mean day essentially never crosses a threshold. What is served here is a raw counted fraction, not a calibrated probability — no bias correction or statistical post-processing is applied, and members_total is served on every day so the number can be audited.

### Before your agent buys a vehicle

Vehicle checks backed by NHTSA vPIC, RappelConso, the EU CO2 monitoring dataset (Regulation (EU) 2019/631), the French registration-tax schedules and the official Crit'Air tables — every response carries its provenance.

- [GET /vehicle/co2](https://api.invoket.com/vehicle/co2) — Before your agent prices, imports or compares a European vehicle: get its type-approval CO2 emissions and technical characteristics — WLTP g/km with its dispersion, fuel, engine capacity, power and mass — from the official EU CO2 monitoring data (Regulation (EU) 2019/631, new registrations 2018-2022), keyed by type-approval number or by make, model and year. Every answer states the precision it was matched at ($0.01, free trial: 1 free call per day per payer address)
- [GET /vehicle/critair](https://api.invoket.com/vehicle/critair) — Before your agent plans a route or advises on a vehicle in France: compute its Crit'Air class and current low-emission-zone (ZFE) restrictions from the official classification tables (arrêté du 21 juin 2016), from declared fuel and Euro norm or first registration date ($0.01, free trial: 1 free call per day per payer address)
- [GET /vehicle/lookup](https://api.invoket.com/vehicle/lookup) — Turn a vehicle designation an agent actually holds - 'Renault Clio V', 'VW Golf 2020' - into the make/model/year key that /vehicle/recalls and /vehicle/co2 require, spelled the way the referential spells it. Sources: NHTSA and RappelConso recall campaigns, EEA European registration aggregates. Closed verdict: exact, ambiguous or none. Several model years for one model is the normal answer, and every candidate is returned - we never pick one for you. ($0.01, free trial: 1 free call per day per payer address)
- [GET /vehicle/prepurchase](https://api.invoket.com/vehicle/prepurchase) — Before your agent buys a used vehicle: one VIN returns a decision - ok, review, stop, insufficient_coverage - over open recall campaigns (NHTSA, RappelConso), type-approval CO2 from the European Environment Agency, Crit'Air low-emission-zone class and what the French registration certificate would cost. Every reason names its block; the answer states what it cannot attest - service history, mileage, liens, accident damage. ($0.25, free trial: 1 free call per day per payer address)
- [GET /vehicle/recalls](https://api.invoket.com/vehicle/recalls) — Before your agent buys, sells or services a vehicle: list manufacturer recall campaigns that may affect it, consolidated from official NHTSA and RappelConso sources, matched by make, model and year or from a VIN. An empty list means no known recall. Results are paged at 200 campaigns, one paid call per page: the busiest brands (~900 campaigns) take 5 ($0.01, free trial: 1 free call per day per payer address)
- [GET /vehicle/report](https://api.invoket.com/vehicle/report) — Before your agent buys or appraises a vehicle: one consolidated report from a VIN — decode, candidate recall campaigns, type-approval CO2, the French registration tax it would cost and, from declared characteristics, Crit'Air / low-emission-zone status — from official NHTSA vPIC, RappelConso, EU 2019/631 and French tax sources, each block with its own provenance and honest coverage ($0.10, free trial: 1 free call per day per payer address)
- [GET /vehicle/tax](https://api.invoket.com/vehicle/tax) — Before your agent buys, imports or quotes a vehicle in France: compute what registering it costs — CO2 malus, weight malus and the regional certificate tax — against the official schedule in force on the registration date you supply, not the one a model remembers. Coverage is France only; each item states its bracket, its threshold and the exemption applied with its legal article, and the total disappears rather than being partial ($0.01, free trial: 1 free call per day per payer address)
- [GET /vehicle/vin/decode](https://api.invoket.com/vehicle/vin/decode) — Before your agent buys, lists or insures a vehicle: decode any 17-character VIN offline — manufacturer, country and region of build, model year, check digit validity and deterministic attributes from the official NHTSA vPIC tables ($0.01, free trial: 1 free call per day per payer address)

### Before your agent books an invoice

E-invoice checks backed by the EN 16931 semantic model and the official Factur-X, CII and UBL specifications, plus the fiscal verdicts of Directive 2006/112/EC (VAT) and Directive 2011/7/EU (late payment) — every response carries its provenance.

- [POST /invoice/generate](https://api.invoket.com/invoice/generate) — Before your agent bills a customer: get the invoice document itself, ready to send and archive - not a verdict on someone else's file. Post simple business JSON (parties, lines, VAT), receive XML already cleared by the full official EN 16931 rule set, totals computed, inconsistent input refused field by field. CII by default (Factur-X EN 16931 URN), syntax=ubl for UBL 2.1, ruleset=peppol for Peppol BIS Billing 3.0. vat_treatment writes the reverse charge or intra-Community exemption mention. ($0.10, free trial: 1 free call per day per payer address)
- [POST /invoice/generate-pdf](https://api.invoket.com/invoice/generate-pdf) — Before your agent bills a customer: get the whole Factur-X file it sends and the customer reads - a PDF/A-3B embedding the EN 16931 CII XML, the hybrid invoice mandated by the French 2026-2027 reform. Post simple business JSON (parties, lines, VAT), get a file ready to send and archive: totals computed, inconsistent input refused field by field, the official rule set cleared and the embedded XML re-read byte for byte. vat_treatment writes the reverse charge or intra-Community exemption mention. ($0.10, free trial: 1 free call per day per payer address)
- [POST /invoice/late-payment](https://api.invoket.com/invoice/late-payment) — Before your agent sends a dunning letter or books a receivable: what is legally due on an unpaid B2B invoice. Post the claim (amount, currency, country, due date - or invoice date plus agreed terms - and payment date) and get late-payment interest computed PERIOD BY PERIOD under Directive 2011/7/EU: the reference rate changes every 1 January and 1 July, so a claim straddling several half-years is split into tranches, each at the rate of its own half-year - applying today's rate to the whole period is simply wrong. Statutory rate = ECB main refinancing rate (NBP reference rate for Poland) plus the national margin, with the national transposition actually applied: France 10 points, Germany 9 on the Basiszinssatz base, Belgium rounding the reference up to the half point, 8 points elsewhere. Covers FR, DE, ES, IT, NL, BE, PT and PL, with an explicit fallback to the Directive minimum for the other Member States - a national rule is never guessed. Adds the fixed recovery compensation of Art. 6 (EUR 40, tiered in Poland), each component cited to its article. Paying on time is a valid answer, not an error. ($0.01, free trial: 1 free call per day per payer address)
- [POST /invoice/read](https://api.invoket.com/invoice/read) — Read any EU structured e-invoice in one call: post a Factur-X PDF, CII or UBL XML and get faithful structured data - parties with SIREN/VAT identifiers, line items, VAT breakdown, totals, payment IBAN and due dates. Covers the three formats mandated by the French 2026-2027 e-invoicing reform (EN 16931). No account, no key, no OCR guesswork. ($0.01, free trial: 1 free call per day per payer address)
- [POST /invoice/validate](https://api.invoket.com/invoice/validate) — Should you accept this invoice? Post a Factur-X PDF, CII or UBL XML and get a deterministic EN 16931 verdict: XSD conformance, every violated business rule by its official BR id with observed vs expected values, Factur-X profile consistency, and syntax checks on IBAN, SIREN/SIRET and VAT identifiers. The formats mandated by the French 2026-2027 reform. A non-conformant invoice is a paid, documented answer - no LLM guesswork. Add ?ruleset=xrechnung or ?ruleset=peppol to layer a national CIUS pack on top of the EN 16931 base: XRechnung (German BR-DE rules, DE mandate) or Peppol BIS Billing 3.0 (BE mandate, live since 2026-04), each violation sourced by its official id (BR-DE-xx, PEPPOL-EN16931-Rxxx). Each verdict also carries informational VAT consistency checks (INV-VAT-*), never mixed with the normative BR ids. ($0.01, free trial: 1 free call per day per payer address)
- [POST /invoice/vat-treatment](https://api.invoket.com/invoice/vat-treatment) — Before your agent issues or books a cross-border invoice: who charges the VAT, under which mechanism, where the supply is taxed and with which compulsory wording. Post one transaction (countries, goods or services, business or consumer customer, supply kind, date, optional amount) and get a determination sourced article by article under Directive 2006/112/EC: place of supply, person liable, standard VAT, reverse charge, intra-Community exemption or out of scope, the rate in force at that date, and the exact invoice mentions to print. An invoice missing its reverse-charge mention passes the EN 16931 rules and is still refused by the tax authority - the check /invoice/validate cannot make. The customer's VAT number is taken AS DECLARED (zero network): verify it live with /company/vat. Uncovered regimes (OSS/IOSS, import VAT, margin schemes, triangulars) come back as a motivated undetermined, never a plausible default. ($0.01, free trial: 1 free call per day per payer address)
- [POST /invoice/vat-treatment/batch](https://api.invoket.com/invoice/vat-treatment/batch) — A sales ledger or an order book judged in one call: up to 200 transactions, one VAT determination each, one settlement. Same verdicts as /invoice/vat-treatment - place of supply, person liable, standard VAT, reverse charge, intra-Community exemption or out of scope, the rate in force at the date of each line, the compulsory invoice mentions and the articles of Directive 2006/112/EC they rest on. A malformed item is reported at its position instead of failing the batch; only an empty or oversized batch is a 400. Legal bases and caveats are shared across the batch and cited by key, and the summary counts the five mechanisms. Customer VAT numbers are taken AS DECLARED (zero network by design) - verify them with /company/vat; uncovered regimes (OSS/IOSS, import VAT, margin schemes, triangular transactions) come back as a motivated undetermined, never a plausible default. ($0.005 + $0.005/item)

### Before your agent onboards a counterparty

Counterparty due-diligence checks backed by the official INSEE Sirene register, the BODACC gazette, VIES, the Peppol directory and the global GLEIF LEI reference — every response carries its provenance.

- [GET /company/events](https://api.invoket.com/company/events) — Check a French company for official insolvency, deregistration and business-sale announcements before you invoice or extend credit: dated event timeline and factual flags from the official BODACC gazette, by SIREN. An empty list is a paid answer: no known announcement over the covered window. No account, no key. ($0.01, free trial: 1 free call per day per payer address)
- [GET /company/lei](https://api.invoket.com/company/lei) — Identify the company behind a bank identifier, a French SIREN, an ISIN or an exact name before you onboard, pay or invoice it: official GLEIF LEI identity - legal name, jurisdiction, entity and registration status, addresses, national registration number, mapped BICs and ISINs. Lookup by LEI, BIC (8 or 11), ISIN, SIREN, or exact legal name plus country. Homonyms are returned as candidates, never silently resolved. ($0.01, free trial: 1 free call per day per payer address)
- [GET /company/ownership](https://api.invoket.com/company/ownership) — Find out who controls a counterparty before you onboard, pay or invoice it: the declared control chain from the official GLEIF Level 2 reference, by LEI - direct parent, ultimate parent, the dated chain between them, and direct subsidiaries. A declared absence of parent comes back with its official reason, never as an empty block. This is the accounting consolidation parent, not beneficial ownership. ($0.01, free trial: 1 free call per day per payer address)
- [GET /company/peppol](https://api.invoket.com/company/peppol) — Check whether a company can receive e-invoices on the Peppol network before you send one: participant identifiers and accepted document types from the official Peppol Directory export, by SIREN, SIRET or explicit Peppol participant ID.

Lookup by SIREN or SIRET. No account, no key, pay per call. ($0.01, free trial: 1 free call per day per payer address)
- [GET /company/vat](https://api.invoket.com/company/vat) — Validate any EU VAT number live against the official European Commission VIES service before you invoice cross-border, or derive and check the French VAT number from a SIREN. Returns valid/invalid or an honest 'unverifiable' when the member state is down - syntax check always included. No account, no key. ($0.01, free trial: 1 free call per day per payer address)

### Before your agent acts on a prescription

Medication checks backed by the French BDPM (ANSM/HAS) register and the US openFDA and RxNorm datasets - every response carries its provenance.

- [GET /medication/availability](https://api.invoket.com/medication/availability) — Check a medication's availability before your agent orders or substitutes it: shortage reports from the French ANSM (data.ANSM) by CIS code or substance (INN/DCI) - status (rupture, risque_rupture, tension, remise_a_disposition, arret_commercialisation, or no_known_shortage), report dates, expected return and the official ANSM report URL. Honest by design: ANSM only records reported shortages, so the absence of a report is never a stock guarantee. French market scope: a US NDC key returns an honest FR-only coverage note. No account, no key, pay per call. ($0.01, free trial: 1 free call per day per payer address)
- [GET /medication/generics](https://api.invoket.com/medication/generics) — Find the French BDPM generic group of a medication before your agent substitutes or sources it: given a CIS code, exact name or DCI substance, returns the group's principle brand (princeps) and every equivalent generic, each with its role (princeps/generique), official name and pack-level public price and reimbursement rate when the BDPM publishes them. French (BDPM) scope: a US NDC key returns an honest FR-only coverage note. No account, no key, pay per call. ($0.01, free trial: 1 free call per day per payer address)
- [POST /medication/interactions](https://api.invoket.com/medication/interactions) — Check drug-drug interactions against the authoritative French ANSM thesaurus before your agent acts on a prescription or an order: post 2+ medications (CIS code, US NDC, INN/DCI substance or ANSM class) and get every published interaction between them - constraint level (contre_indication, association_deconseillee, precaution_emploi, a_prendre_en_compte), management advice and mechanism exactly as published by ANSM, plus honest coverage of anything that could not be compared. US drugs join via the INN substance bridge. No account, no key, pay per call. ($0.01, free trial: 1 free call per day per payer address)
- [GET /medication/lookup](https://api.invoket.com/medication/lookup) — Turn a medication name an agent actually holds - 'Doliprane 1000', 'Tylenol', 'paracetamol' - into the CIS code, product NDC or canonical active-substance identifier that /medication/resolve, /medication/interactions, /medication/generics and /medication/availability require. Sources: the French BDPM register and openFDA/RxNorm. Closed verdict: exact, ambiguous or none. One brand name covering several strengths and forms is the normal answer, and every candidate is returned - we never pick one for you. ($0.01, free trial: 1 free call per day per payer address)
- [GET /medication/report](https://api.invoket.com/medication/report) — One consolidated medication report before your agent acts on a prescription or an order, by French CIS code or US NDC: official BDPM identity with pack-level price and reimbursement, INN-normalized substances, BDPM generic group, ANSM shortage status, and ANSM-thesaurus drug-drug interactions between the subject and an optional co-medication list (with=, comma-separated CIS/NDC/DCI). Every section carries its own source and date; honest coverage. No account, no key, pay per call. ($0.10, free trial: 1 free call per day per payer address)
- [GET /medication/resolve](https://api.invoket.com/medication/resolve) — Resolve a medication before your agent acts on a prescription or an order: official identity from the French BDPM registry (ANSM/HAS) by CIS code, exact name or DCI substance - authorization and marketing status, active substances normalized to INN (the FR-US bridge), pack-level price and reimbursement rate, generic group. Same endpoint resolves US drugs by NDC or name (openFDA/RxNorm). No account, no key, pay per call. ($0.01, free trial: 1 free call per day per payer address)

### Before your agent ships an EU label

EU labelling verdicts backed by the ECHA Annex VI harmonised classification (CLP) versioned by ATP, the cosmetics Regulation (EC) No 1223/2009 and the food-additive Union list of Regulation (EC) No 1333/2008 — every response carries its provenance.

- [GET /label/chem/classify](https://api.invoket.com/label/chem/classify) — Before your agent approves a substance for an EU label or safety data sheet: the harmonised classification and labelling from Annex VI of the CLP regulation (ECHA), by CAS, EC number or exact name - hazard classes with H statements, GHS pictograms, signal word, concentration limits, versioned by ATP: the entry in force at the queried date, plus the upcoming change when a published but not-yet-applicable ATP modifies it. Absence from Annex VI returns an explicit self-classification verdict. ($0.01, free trial: 1 free call per day per payer address)
- [POST /label/chem/classify/batch](https://api.invoket.com/label/chem/classify/batch) — Before your agent clears a BOM or a formulation for the EU market: screen up to 200 substances in one call against Annex VI of the CLP regulation (ECHA) - one harmonised-classification verdict per item (CAS, EC number or exact name) with H statements, GHS pictograms, signal word, and the ATP version in force plus upcoming ATP changes; a malformed item is flagged at its position instead of failing the batch, and an unlisted substance gets an explicit self-classification verdict. ($0.005 + $0.005/item)
- [GET /label/chem/svhc](https://api.invoket.com/label/chem/svhc) — Before your agent clears a substance, an article or a supply-chain declaration for the EU market: is it on the ECHA Candidate List of substances of very high concern (SVHC, REACH)? By CAS, EC number or exact name - the published entry with its Article 57 inclusion reasons (CMR, PBT, vPvB, equivalent concern), inclusion date and the ECHA inclusion decisions as published, plus the generic obligations it triggers (REACH Article 33 information duty, SCIP notification above 0.1 % w/w). A not-listed verdict is dated to the served list, never an all-clear. ($0.01, free trial: 1 free call per day per payer address)
- [POST /label/chem/svhc/batch](https://api.invoket.com/label/chem/svhc/batch) — Before your agent clears a BOM, a formulation or a supplier declaration for the EU market: screen up to 200 substances in one call against the ECHA Candidate List of SVHC (REACH) - one verdict per item (CAS, EC number or exact name) with the published Article 57 inclusion reasons, inclusion date and the triggered obligations (REACH Article 33, SCIP notification); a malformed item is flagged at its position instead of failing the batch, and a not-listed substance gets an explicit verdict dated to the served list. ($0.005 + $0.005/item)
- [POST /label/claims/check](https://api.invoket.com/label/claims/check) — Before your agent puts a nutrition or health claim on an EU food label: is the proposed wording an authorised claim (exact legal wording + conditions of use), a non-authorised one (official rejection reason + EFSA opinion), or absent from the EU Register (Regulation (EC) 1924/2006)? Post the label wording (and optionally the nutrient); matching is strict-normalised (case, punctuation, spacing), exact or containment, never fuzzy - zero false positives. The Register carries the REJECTED claims a plain LLM validates by mistake. An absent wording returns the authorised claims for the nutrient plus a limit note (absence is neither authorisation nor prohibition - 'on hold' botanicals are not in the Register). ($0.01, free trial: 1 free call per day per payer address)
- [GET /label/claims/permitted](https://api.invoket.com/label/claims/permitted) — List the authorised EU nutrition and health claims for a given nutrient or substance (Regulation (EC) 1924/2006): what your agent may legally write on a food label. Pass the nutrient; get every authorised claim as published - exact legal wording, conditions of use, EFSA opinion and legislation. A known nutrient whose claims are all rejected returns an explicit empty list with the rejected count (not a silent gap); a nutrient absent from the Register returns an empty list with a limit note (absence is neither authorisation nor prohibition - 'on hold' botanical claims are not in the Register). The counterpart of /label/claims/check: check starts from a wording, permitted starts from the nutrient. ($0.01, free trial: 1 free call per day per payer address)
- [GET /label/cosmetic/ingredient](https://api.invoket.com/label/cosmetic/ingredient) — Before your agent clears an ingredient for an EU cosmetic label: is it prohibited (Annex II), restricted (Annex III), or authorised as a colorant (IV), preservative (V) or UV filter (VI) under Regulation (EC) No 1223/2009? By CAS, EC number, INCI name or exact chemical name - every published entry with its maximum concentration, conditions of use and the MANDATORY LABEL WORDING served word for word, versioned by amending regulation: the consolidated version in force at the queried date plus the upcoming change when a published but not-yet-applicable one modifies the entry. CosIng is a legally non-binding information tool: only the Annexes are authoritative, and any divergence is reported, never silently resolved. Absence from the Annexes is not an authorisation - the verdict says so explicitly. ($0.01, free trial: 1 free call per day per payer address)
- [POST /label/cosmetic/ingredient/batch](https://api.invoket.com/label/cosmetic/ingredient/batch) — Before your agent clears a cosmetic formulation for the EU market: screen a whole INCI list - up to 200 ingredients in one call - against Annexes II to VI of Regulation (EC) No 1223/2009. One verdict per item (prohibited, restricted, authorised colorant/preservative/UV filter, or not listed) with the published entries, maximum concentrations, conditions and MANDATORY label wording served word for word, plus a summary count per verdict. A malformed item or an unresolved identity is flagged at its position instead of failing the batch; the input order is preserved but no conclusion is drawn from it (an INCI list's descending-concentration order is not exploited). This is not a formulation compliance verdict: no concentration in the finished product is computed. ($0.005 + $0.005/item)
- [GET /label/food/additive](https://api.invoket.com/label/food/additive) — Before your agent validates a recipe, a food label or an import: is this additive authorised in this food category, at what maximum level and under which conditions (Union list, Regulation (EC) No 1333/2008, Annexes II and III)? By E number or exact published name, WITH a food category code - you get an authorised/not_authorised verdict with the maximum level, restrictions and footnotes served word for word ('quantum satis' as published, never converted), and via_group when the authorisation comes from a published group such as 'E 249 - 250'. WITHOUT a food category you get the inventory of categories where it is authorised and NO verdict: an additive has no status in the abstract. A not_authorised verdict is dated - the Union list is positive. Where the text bounds a line by a 'Period of application', the lines that apply at your date come first and each one carries in_force_at_date: an expired line is flagged, never dropped. ($0.01, free trial: 1 free call per day per payer address)
- [GET /label/lookup](https://api.invoket.com/label/lookup) — Turn an ingredient name read off a label - 'sodium nitrite', 'titanium dioxide', an INCI name - into the exact CAS, EC, INCI or E number that /label/chem/classify, /label/chem/svhc, /label/cosmetic/ingredient and /label/food/additive require. Sources: ECHA Annex VI and Candidate List, the consolidated Cosmetics and Food Additives Regulations, and the Commission CosIng index. Closed verdict: exact, ambiguous or none, and every candidate names the endpoints it opens. ($0.01, free trial: 1 free call per day per payer address)
