French financial regulator alerts

A different question from sanctions screening, and a different source: here you are looking for fraud and impersonation, not asset freezes. It is the check to run before entrusting money to anyone presenting themselves as a financial intermediary.

What the route returns

Catalogue description, exactly as agents read it:

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.

Expected identifier

A name, or a 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.

Price and billing

Price: $0.01. 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.
