Check exactly one seller or buyer's registry identifiers and readiness through EU Verify. Use to correct one party's identifiers; use check_invoice_parties to check seller and buyer together, or validate_invoice for document rules. Supply siren, siret or vat; siret wins over siren. A SIREN/SIRET, country_code=FR or FR VAT triggers French checks requiring a SIREN/SIRET. Omitted vat can be derived from a successful French lookup; foreign parties normally need explicit VAT. Send address fields with a coherent country_code; requester_vat cannot substitute for the checked party's vat. Sends supplied fields to EU Verify and applicable registers. A Pro/Scale key enables checks; other plans return plan_excluded. No Factur-X document quota is consumed. Returns status, reasons with field pointers and available evidence: invoice_ready is positive, not_ready needs correction, upstream_unavailable is inconclusive and retryable, invalid_input indicates rejected input. Register results and evidence ids may change between calls. No invoice is created or stored.
