# 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](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) 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](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
