What the route returns
Catalogue description, exactly as agents read it:
European supplier and invoice verification for e-invoicing compliance in Belgium (mandate since 1 Jan 2026) and Poland (KSeF): registry identity, VIES VAT check, Peppol reachability (BE), IBAN form + key, bank and, in Poland, the official White List: is the IBAN DECLARED by the taxpayer? Paying an undeclared account over 15,000 PLN costs the VAT deduction and joint liability. Natural person or doubtful form (BE, PL): no name or address (ecartes). Deterministic verdict, closed-list reasons.
Price and billing
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.
What this route does not do
Scope limited to Belgium (mandate live since 1 January 2026) and Poland. For France, use the French invoicing-pack route; for other states, VAT validation alone.

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.

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.
