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.
