What it does

IBAN verification and bank validation for SEPA payments: a FORM check to verify a supplier before payment — ISO 13616 structure + mod-97 key, plus bank identification from FREE official sources (FR via ACPR/REGAFI incl. LEI and SIREN; BE NBB; AT OeNB incl. LEI; NL BIC list; DE Bundesbank file). French BICs via GLEIF/SWIFT BIC-to-LEI. NOT a payee verification for instant payments: neither the holder name nor the account's existence is checked (verification_titulaire: non_disponible).

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/30415.json for the price and payment options.
Pay. Call GET https://api.sirenic.eu/v1/iban/verifier/:iban. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
