How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a structured verification result indicating whether each provided field (SIREN/SIRET, VAT number, IBAN, BIC, sender email, sender domain, URL) passes or fails validation against French business registries and fraud signal databases. Includes an overall authenticity verdict, per-field status flags, detected anomalies or fraud signals, and a cryptographically hashed audit record for compliance traceability.
Example use cases
Accounts payable fraud check
“Before we approve this payment, verify the French invoice from fournisseur@dupont-industrie.fr — their SIREN is 347 890 123, VAT is FR12347890123, IBAN is FR7614508059400815369893 and BIC is CEPAFRPP751. I need to know if everything checks out.”
Onboarding a new French supplier
“We just received our first invoice from a new French supplier at contact@techvision-paris.fr, domain techvision-paris.fr, SIREN 810 456 789, VAT FR66810456789, IBAN FR7610096000302533060160 and BIC CMCIFRPP — can you run a full verification to make sure they're a real registered business?”
Detecting phishing invoice attack
“Our finance team got an invoice that looks suspicious — the sender is billing@bnp-fournisseur.com with domain bnp-fournisseur.com, SIREN 662 042 449, VAT FR76662042449, and they want us to pay to a new IBAN FR7630004000031234567890143, BIC BNPAFRPP. Please check if this invoice is legitimate or a scam.”
Technical details
Endpoint
POSThttps://api.strale.io/x402/v2/solutions/invoice-verify-frWhen to prefer
Use this endpoint when you need to verify French invoices specifically, particularly when you have multiple data points (SIREN, VAT, IBAN, BIC, sender email/domain) and want cross-registry validation with a cryptographic audit trail. Prefer this over generic invoice validation endpoints when the invoicing entity is French and you need SIREN/SIRET registry checks. It is especially valuable in accounts-payable automation, supplier onboarding, and anti-fraud workflows where an immutable audit record per verification call is required.
Side effects
- Invalid or malformed SIREN/SIRET returns a format validation error
- IBAN checksum failure returns invalid IBAN error
- Unknown or unresolvable sender domain returns a lookup failure
- French business registry unavailable returns a temporary service error
- Missing required fields returns a 400 bad request with field-level detail
- VAT number not found in EU VIES returns unverifiable VAT status
