How this service works
One-call compliance check for the French e-invoicing reform (from 2026-09-01 the customer's SIREN is a mandatory invoice mention). Query: ?siren=552032534 or ?siret=55203253400041. Runs the Luhn checksum, confirms existence and active status in the official SIRENE registry, computes the FR VAT number and validates it live against VIES. Returns a single verdict: ready / not_ready / check_vat_manually (VIES flakiness never blocks the answer). 1h cache.
Output
Returns a single verdict string ('ready', 'not_ready', or 'check_vat_manually'), along with Luhn checksum result, SIRENE existence and active status, computed French VAT number, and live VIES validation result. Response is cached for 1 hour.
Example use cases
Example prompt
“Before I send an invoice to this French supplier, can you check if their SIREN 552032534 is active in the SIRENE registry and whether they're ready for the 2026 French e-invoicing reform — including their VAT number validation?”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/fr/invoice-readyWhen to prefer
Use this endpoint when you need a single authoritative compliance verdict for French e-invoicing (mandatory from 2026-09-01) that combines SIRENE registry lookup, Luhn checksum, VAT number computation, and live VIES validation in one call. Prefer over rolling your own multi-step validation when you need a quick go/no-go answer before issuing or accepting a French B2B invoice.
Side effects
- Missing both siren and siret query parameters — returns error requiring at least one
- Invalid SIREN format (not 9 digits or fails Luhn) — returns not_ready with checksum failure detail
- SIREN not found in SIRENE registry — returns not_ready
- VIES service unavailable — returns 'check_vat_manually' verdict rather than blocking
- Malformed SIRET (not 14 digits) — returns validation error
