The only route available in France to approach ownership, the beneficial-ownership register no longer being public. A proof guard frames the extraction: a clause is served only if its keyword actually appears in the document's text — a guard added after a non-existent pre-emption clause was produced for a real company.

Catalogue description, exactly as agents read it:
Ownership and share capital structure of a French company from the official INPI registry: AI extraction of the latest PUBLIC articles of association filed at INPI — share capital amount, legal form, shareholders (name, role, birth YEAR, ownership %), notable clauses, with a confidence level and the source document reference. Due diligence from public filed deeds — NOT a beneficial-ownership register (RBE) and not a beneficial-owner identification. Immutable document: extracted once, cached.
9-digit company number.
A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.
Dated snapshot from 2026-07-29, truncated to one item per array. It is not live data. The full extract is served free of charge from the samples surface, and the schema from the OpenAPI document.

}Price: $0.35. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.
An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

claude mcp add --transport http sirenic https://api.sirenic.eu/mcpThis is not a beneficial-ownership register and does not replace one. Filed articles can be old: an unpublished share transfer does not appear. The document is immutable, extracted once then cached — read it as a dated exhibit, never as the current shareholding.
/v1/entreprise/{siren}/documents — $0.02/v1/eu/entreprise/GB/{company_number}/beneficiaires-effectifs — $0.02Every 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.

The ownership data served for France is not a beneficial-ownership register and does not replace one: the French register has not been publicly accessible since the 2022 ruling of the Court of Justice of the European Union. What is served comes from publicly filed deeds.
