Invoice verification — cross-check the identifiers printed on a French invoice

Invoice verification for France — cross-check the identifiers PRINTED ON an invoice in one call: SIREN against the official registry (existence, active status, live), the VAT number on the invoice against the one computed from the SIREN AND live against VIES, the IBAN (ISO form, key digits, bank identified). Deterministic verdict coherent/incoherent/inverifiable, closed-list reasons. Flags a VAT that belongs to another company or a ceased supplier. Not a payee verification. Preserve coverage and provenance. Missing data is not zero; a name match is not proof of identity.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
