Verify a supplier before payment — France (e-invoicing mandate, 1 September 2026)

Invoice verification and supplier verification — verify supplier before payment in France, the invoicing pack of the e-invoicing mandate France September 2026 (all VAT-liable companies must receive): legal identity, obligation dates, intra-EU VAT number checked LIVE against VIES, IBAN form + key check, bank identified, deterministic pret_a_facturer verdict, closed-list reasons. Not a payee verification: no holder name, no account existence check. A VIES outage never yields a false invalid. 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.
