“They told me they were authorised” is not a check. /v1/entreprise/{siren}/agrements queries three official registers by company number and returns authorisation dates, licensed services, European Economic Area passporting and withdrawals. 47,731 authorisations are in the database, from 9 authorities.

| Question | Route |
|---|---|
| Is this company a payment institution, e-money institution, account-information provider, agent or exempt entity? | /v1/entreprise/{siren}/agrements (EBA register, daily) |
| Is it an insurance undertaking? | same route (EIOPA register) |
| Is it an electronic-communications operator? | same route (ARCEP) |
| Is it an investment firm or a fund manager, anywhere in Europe? | /v1/eu/agrements (ESMA registers, by name or LEI) |
| Is it blacklisted or impersonating someone? Is it a registered digital-asset provider or a licensed French asset manager? | /v1/regulateurs/fr/alertes (French market authority open data, daily) |
The absence of an authorisation is returned as 200, not 404. That is an explicit choice: knowing a company is not authorised is precisely the information that triggers a decision, and a 404 would be indistinguishable from a fault on our side. So you pay for a check, not for a hit.
Same logic on the lobbying register: “not registered” is a full answer there, served as 200.
A provider authorised in another member state can operate in France without a French authorisation: that is passporting, and a check limited to national registers misses it. So the response returns both the licensed services and the passporting, letting you tell an unauthorised player from one authorised elsewhere.
Two routes complete the picture of a counterparty without costing much. /v1/entreprise/{siren}/lobbying returns the profile in the official interest-representatives register: status, category, expense brackets per year, recent subjects, clients for consultancies, declaration failures. Organisation level only, with no personal data.
/v1/entreprise/{siren}/risques-industriels links the company to regulated industrial sites: 138,020 installations are in the database, including Seveso classification — an environmental due-diligence angle standard company records ignore.
Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.
Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.
Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.

claude mcp add --transport http sirenic https://api.sirenic.eu/mcp| Route | Price | What it returns |
|---|---|---|
/v1/entreprise/{siren}/agrements (free sample) | $0.02 | Regulatory authorisation and licences held by a French company, by SIREN: payment institution, e-money institution, account-information provider, payment agent or exempt entity from the EBA PSD2 register (daily), insurance undertaking from EIOPA, telecom operator (electronic-communications operator, ARCEP). Returns authorisation dates, licensed PSD2 services, EEA passporting and withdrawals — a compliance check across three official registers. Not authorised is a paid answer too (200). |
/v1/eu/agrements (free sample) | $0.01 | EU financial authorisation lookup in the official ESMA Registers: search ~14,000 MiFID-regulated entities across the EU/EEA (investment firms, UCITS/AIFM managers) by name or LEI — authorisation status of the regulated entity, home and host member states, competent authority, authorisation dates. One integration covers all 27+ countries of Europe: an investment firm and regulated entity KYB check for the whole single market. Data freely available at the source (ESMA). |
/v1/regulateurs/fr/alertes (free sample) | $0.01 | French financial regulator alerts and scam check against the official AMF blacklist: screen a name for unauthorized investment websites, scams and AMF impersonation, and look up PSAN crypto provider registrations and licensed asset management companies (SGP) by name or SIREN. A compliance screening of the regulator blacklists for agents vetting French counterparties in crypto and asset management. Official AMF open data (Licence Ouverte 2.0), refreshed daily. |
/v1/entreprise/{siren}/lobbying (free sample) | $0.01 | Lobbying and influence profile of a French company from the official HATVP register of interest representatives — a transparency, governance and ESG due diligence signal: registration status, category, lobbying-expense brackets per fiscal year, staff count, recent subjects with intervention domains and action types, clients (for consulting firms), affiliations, declaration defaults and deregistrations. Organisation-level only — no personal data. Not registered is a meaningful answer (still 200). |
/v1/entreprise/{siren}/risques-industriels (free sample) | $0.01 | Industrial risk and environment profile of a French company from the official ICPE register (Géorisques/DGPR): classified facilities with Seveso status (upper/lower tier), authorisation regime, activity state, IED flag, nomenclature rubrics and a risk synthesis per SIREN — an ESG and environmental compliance signal on hazardous sites operated by the company. A company with no classified facility returns level aucun (still 200) — the clean answer is the signal. |

Yes, with its withdrawal date. That is often the most useful part of the check: a player still operating after a withdrawal is a strong signal.
