Fuentio: UK, France & Spain company data from official registries

Fuentio: UK, France & Spain company data from official registries

Verify UK, French and Spanish companies from official registries, with source, check date and receipt on every answer.

Fuentio gives AI agents and compliance teams clean company data for the United Kingdom, France and Spain, straight from official sources: Companies House for the UK (every company, with insolvency cases, charges and latest filings), INSEE Sirene and the national register for France, BORME (Registro Mercantil acts since 2009) for Spain, and GLEIF for LEIs and group links. Every answer carries the source, link, check date and a receipt you can show an auditor. Connect with just the URL; free tier, no card.

https://api.fuentio.com/mcp

Ask your agent "Verify the UK company 00445790 for onboarding.", "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

• UK company lookup, search and verification from Companies House (company number or name), including dissolved companies, insolvency cases, charges and latest filings.
• Company lookup and search for France (SIREN, SIRET, name) and Spain (company name, BORME acts since January 2009).
• One record per real company, matched across registers and GLEIF, with the reason for every match and every non-match.
• Company group links (parent and subsidiary companies reported to GLEIF).
• Company history: what changed and when.
• A verify_company check for onboarding (KYB): status, address, identifiers and evidence in one 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 receipt id.
• When sources disagree, you see both values, never a silent pick.
• Short answers by default, errors that say exactly what to retry.
