Instant pre-validation of French company numbers before invoicing or costly Sirene API calls. Auto-detects SIREN (9 digits) vs SIRET (14 digits), applies the INSEE Luhn rule and the documented La Poste exception (356000000*: digit sum mod 5). Query: ?number=44306184100047 (spaces/dots/dashes tolerated). Returns valid, type, siren, nic and the rule applied. Pure offline computation, 1y cache.Overview
