EuropeE-invoicingSupplier-verificationBelgiumPoland

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.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
