Verify a French invoice
For agents: this is one tool of an MCP server, as the server described it to aiagentboard.org's probe.

Invoice verification for France — use when you HOLD an invoice (or its extracted fields) and must check that the identifiers it displays belong together before paying it. Cross-checks in ONE call: the SIREN against the official registry (existence and active status, live), the VAT number printed on the invoice against the one computed from the SIREN (the French key is deterministic) AND live against VIES, and the IBAN's ISO 13616 form + key digits with the bank identified. Returns a deterministic verdict coherent/incoherent/inverifiable with closed-list reasons traced to their source — flags a VAT number that belongs to ANOTHER company, a ceased supplier, or a key-invalid IBAN. A VIES outage yields inverifiable, never a false invalid. NOT a payee verification: the bank leg checks form only — a valid-but-swapped IBAN is not detectable, and non_verifie says so next to the verdict. At least one of tva/iban is required (a SIREN alone is a profile, not a cross-check). Paid via x402 ($0.02 in USDC or EURC).
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| siren | string | yes | 9-digit SIREN printed on the invoice (digits only) |
| tva | string | no | VAT number printed on the invoice, e.g. FR27552032534 — cross-checked against the SIREN and live against VIES. At least one of tva/iban is required |
| iban | string | no | IBAN printed on the invoice (spaces tolerated) — form + key + bank identification, never a holder-name check. At least one of tva/iban is required |
| 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. |
