# ENTIA Systems > Trust Infrastructure for AI. Verified business entity data and socioeconomic > profiles across 34 countries, with structured provenance from official sources > (AEAT, INE, SEPE, Catastro, MITECO, CNMC, Companies House, GLEIF, VIES, BORME). > 5,557,415 verified entities. Every page below exposes Schema.org JSON-LD. ## Crawl & access policy This site uses an edge-cached serving model.
