The answer to the classic complaint about narrow APIs: “I have to call five routes”. Here you pick the blocks and pay for those only. It is the middle ground between one very rich but costly record and a set of calls to orchestrate.

Catalogue description, exactly as agents read it:
Full French company file in ONE call: identity is the base, then add the blocks you want and pay only for those — etablissements, alertes_bodacc, finances, marches_publics, marches_publics_ue, lobbying, risques_industriels, agrements, pi, documents, facturation_prep, score. Example: blocs=finances,pi,score on siren 552032534. Each block costs what its own endpoint costs, total capped at $0.35. A block that cannot be served is NAMED with its reason: no data, not disclosable, or upstream outage.
9-digit company number, plus the list of requested blocks.
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 2026-08-11, 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: $0.005. 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.

/v1/kyb/{siren} — $0.15/v1/entreprise/{siren} — $0.005/v1/intelligence/{siren} — $1.00Every 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.
One call, end to end
