With an API key, or without

Without a key, every tool that doesn't need one works on the keyless trial (20 units a day). With a key, send it as an X-API-Key header (or Authorization: Bearer) to use your plan's units and the tools that need a key: sanctions screening of a company's own names, the review report, watching a company, the company group and issue reports. A free key gives 100 units a month.

The 17 tools

As the live server describes them (in English), taken on 12 October 2026.

Find

list_coverage List the countries, ID formats and official sources Fuentio covers. Free, no key.
search_companies Find companies by name in the official registers of France and Spain, 10 per page.
lookup_company Look up one company in its official register by ID: status, address, legal form, activity, source and check date.
get_company_history See what changed at a company, and when: versions with the fields that changed (address, status), each with its official source.

Check

screen_company key Screen a company's own names against sanctions lists: EU Financial Sanctions File, UK Sanctions List, OFAC SDN list, France's registre des gels.
check_insolvency Check a company's insolvency notices and state: France from BODACC (safeguard, reorganisation, liquidation, plans, closures), Spain from BORME insolvency acts.
check_address Validate a company's registered address against the official address base: France via API Adresse (Base Adresse Nationale, IGN).
check_vat Give a company's EU VAT number and how it was obtained. Registration is never checked: the answer links the official VIES page.

Prove

verify_company Verify a company for onboarding, KYB or before paying or signing: an outcome with reasons, checks, warning signals and a proof code you can show an auditor.
get_evidence Show the evidence behind what Fuentio says about a company: for each field, the value served and every competing value with its source, record, retrieval time, source link and record hash; and the match decision behind each link.
resolve_company Decide whether a company you know (an official ID, or a name with a postcode or town) is a company in the official registers, with evidence: candidates each with a decision, linked, possible or rejected, and the reasons.
explain_match Explain why two register records are, or are not, the same company: today's decision with reason codes and evidence, stored decisions, links, and whether they share one Fuentio entity.
review_report key Produce one review-ready report on a company: identity and links with reasons, facts with sources, last year's changes and gaps, and every check at once (insolvency, sanctions, address, VAT).
report_issue key Report an answer you believe is wrong or missing, so Fuentio checks it against the official source.

Watch

what_changed List what changed at a company since a date, from every official record Fuentio holds for it: status, name, address, legal form, and the source's dated events (BORME acts), each with its source and evidence.
watch_company key Watch a company: when its official records change, Fuentio POSTs the changes, signed, to your https endpoint.

Group

get_graph key Show a company's group: its parent and child companies from GLEIF (direct and ultimate parents), company to company, every edge with its source.
