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 29+ public sources (CNMV, OEPM, PLACSP, BDNS, OpenSanctions, CCAA gazettes, CNMC, CENDOJ and more) to expose company search, structured company reports, registry event timelines, officer records, CNAE sector navigation, daily summaries, public-procurement rankings, a v1.4 cross-source trust score, and CSV/JSON exports. The public REST API is free, requires no API key, and is rate-limited per IP. The project is informational and does not replace official Registro Mercantil certificates.
