Fuentio: France & Spain company data from official registries
Official company checks for France and Spain, for AI agents.
Fuentio is a remote MCP server (and REST API) that looks up, searches and verifies companies inFrance and Spain from official registries: INSEE Sirene and the national company register forFrance, BORME (Registro Mercantil acts since 2009) for Spain, and GLEIF for LEIs and companygroup links. Every answer cites its source and check date. No setup, free tier.
https://api.fuentio.com/mcp
Ask your agent "Is this supplier still active?", "Which company is behind this SIREN?" or"¿Sigue activa esta sociedad según el BORME?" and get an answer you can trust and prove.
What you get
- Company lookup and search for France (SIREN, SIRET, name) and Spain (company name, BORME actssince January 2009).
- One record per real company, matched across registers and GLEIF, with the reason for everymatch and every non-match.
- Company group links (parent and subsidiary companies reported to GLEIF).
- Company history: what changed and when.
- A
verify_companycheck for onboarding (KYB): status, address, identifiers and evidence inone call. - Insolvency notices (BODACC for France, BORME for Spain).
- Sanctions list screening with clear coverage notes.
- Change alerts with
watch_company.
Why agents pick it
- Official sources only, never scraped guesses.
- Every answer includes the source, a link, the check date, an uncertainty label and a receiptid.
- When sources disagree, you see both values, never a silent pick.
- Short answers by default, errors that say exactly what to retry.
