IBAN verification and bank validation for SEPA — use when you are about to pay a NEW or CHANGED IBAN, or when onboarding a supplier's bank details, and want the cheapest check of the supplier before payment. Runs a FORM check on the IBAN (ISO 13616 structure + mod-97 key), identifies the bank from FREE official registers (France: name+LEI+SIREN via ACPR/REGAFI; Belgium, Austria, Netherlands: name+BIC; Germany when the Bundesbank file is loaded, incl. LEI where available; French banks get their BIC via the GLEIF/SWIFT BIC-to-LEI mapping). Explicitly NOT a payee verification — the account holder's name is never checked and the account's existence is not tested (verification_titulaire: non_disponible): a well-formed IBAN at an identified bank is no proof that the account belongs to your supplier. The answer says this in machine-readable form next to valide: nature_du_controle (forme | forme_et_registres), non_verifie [account existence, holder name] and exemple_de_documentation — true for IBANs on a published list of known documentation samples, which pass every check; the account's existence is not tested; false is not proof of the contrary. The response is Ed25519-signed and carries provenance[] — one entry per block served, naming the official register actually consulted, its licence and its as_of date. For the full invoicing verdict on a French counterparty, call prepare_french_invoice_file instead. Paid via x402 ($0.005 in USDC or EURC).
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| iban | string | yes | IBAN of the account to check, any ISO 13616 country (spaces and dashes tolerated); bank identification is limited to the registers listed in the tool description |
| x_payment | string | no | Optional signed x402 PAYMENT-SIGNATURE header value. Omit to receive the payment quote. |
| api_key | string | no | Optional Sirenic API key (srn_live_…) to pay with prepaid credits instead of x402 — no wallet needed. Get one at https://api.sirenic.eu/compte. Ignored when x_payment is provided (the signed payment wins). On insufficient balance the tool returns a credits error, not an x402 quote. |
