A company's regulatory authorisations

The angle a national check misses: passporting. A provider authorised in another member state can operate in France without a French authorisation, and a check limited to French registers would wrongly class them as unauthorised. The response returns both.

What the route returns

Catalogue description, exactly as agents read it:

Regulatory authorisation and licences held by a French company, by SIREN: payment institution, e-money institution, account-information provider, payment agent or exempt entity from the EBA PSD2 register (daily), insurance undertaking from EIOPA, telecom operator (electronic-communications operator, ARCEP). Returns authorisation dates, licensed PSD2 services, EEA passporting and withdrawals — a compliance check across three official registers. Not authorised is a paid answer too (200).

Expected identifier

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: $0.02. 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.

What this route does not do

“Not authorised” is a full answer, served as 200 and therefore billed. That is deliberate: knowing a company is not authorised is precisely the information that triggers a decision, and a 404 would be indistinguishable from an outage.

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.
