Identity record of a French company

The base record, and deliberately narrow: it loads neither accounts, nor alerts, nor screening. That is what makes it almost free, and it is the right call when all you need is who you are dealing with and whether the company is still active.

What the route returns

Catalogue description, exactly as agents read it:

Full French company profile by SIREN: official company data from the French company registry (INSEE Sirene / INPI RNE). One company lookup returns legal name, legal form, head-office address, NAF code, workforce bracket, creation date, active or ceased status, officers with name and role, collective agreement and the computed intra-EU VAT number. The core KYB building block for verifying a French counterparty: registry facts for due diligence, compliance and onboarding checks.

Expected identifier

9-digit company number, no spaces.

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.

Price and billing

Price: $0.005. 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.

How you pay

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.
