OpenMercantil API Credentials API manages the API keys on an OpenMercantil account. You can list, create, rotate and revoke opaque omk_* keys. A secret is returned once, and it can only be recovered by replaying an identical Idempotency-Key within 24 hours. It suits developers and teams who build on OpenMercantil's Spanish company data and want to handle key lifecycle in code instead of by hand.
OpenMercantil is an independent public-data API for Spanish company intelligence. It indexes the Boletin Oficial del Registro Mercantil (BORME) and cross-references it with 80+ official public sources. Its public read plane is free and anonymous, with paid Profesional, MAX and Enterprise tiers that raise the quota.
