The check to run before a first transfer, and its most important guarantee: a VIES outage never yields an “invalid”. It yields unavailable, a distinct state, so that a compliant supplier is not blocked by an outage that is not theirs.

Catalogue description, exactly as agents read it:
Invoice verification and supplier verification — verify supplier before payment in France, the invoicing pack of the e-invoicing mandate France September 2026 (all VAT-liable companies must receive): legal identity, obligation dates, intra-EU VAT number checked LIVE against VIES, IBAN form + key check, bank identified, deterministic pret_a_facturer verdict, closed-list reasons. Not a payee verification: no holder name, no account existence check. A VIES outage never yields a false invalid.
Dated snapshot from 2026-08-07, 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: $0.03. 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.

This is not a payee verification: neither the holder's name nor the account's existence is checked. Sirenic is not an accredited e-invoicing platform and issues no invoices.
/v1/facture/verifier — $0.02/v1/tva/verifier/{numero} — $0.003/v1/iban/verifier/{iban} — $0.005/v1/eu/facturation/dossier — $0.03Every 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.

The IBAN check is not a payee verification: neither the account holder's name nor the account's existence is checked (verification_titulaire: non_disponible).
Sirenic is not an accredited French e-invoicing platform (PDP), never accesses the central directory, and neither issues, transmits nor routes any invoice.
No account to create, no key to request: the first step is free and shows you exactly what you would be buying.
