Description, as the server wrote it Check a company's insolvency notices and state: France from BODACC (safeguard, reorganisation, liquidation, plans, closures), Spain from BORME insolvency acts. Use it for credit or supplier checks. Don't use it for sanctions: call screen_company. Inputs: country and identifier, as lookup_company (e.g. 'FR', '441639465'). Returns: state (in_procedure, under_plan, closed, notice_found, none_found, not_covered), procedure, dates, notices with official citations, covered_since. Limits: 1 unit. No notice outside the loaded years is not proof of no procedure. Read-only.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "check_supplier_list" says "list": a word for reading.
Description, as the server wrote it Check a supplier list against the official registers: which suppliers are ok, which need a look and why (e.g. in liquidation since a date, per BODACC), with a proof code each, and a private report link to share. Use it for 2 to 100 suppliers at once, or to read a batch you started. Don't use it for one company: call verify_company. Inputs: rows [{reference, company_name, country, identifier}] (an official ID is best; a name alone counts only with postal_code and street matching one company), or batch_id. Returns: counts by review_state (ok, review, could_not_confirm, not_covered, error), the review rows with reasons, share_url; 'next' when still checking. Limits: 5 units a row (+2 for a name), checks reused 24 h free. A registry check, not KYB or sanctions clearance; no person's name.

Description, as the server wrote it Give a company's EU VAT number and how it was obtained. Registration is never checked: the answer links the official VIES page. Use it to fill an invoice or a supplier file. Don't use it as proof of VAT registration: check it on VIES. Inputs: country and identifier, as lookup_company (e.g. 'FR', '441639465'). Returns: number, origin (published or computed), registration_checked false, note, check_url. Limits: 1 unit. Spain: no VAT numbers published. Read-only.

Description, as the server wrote it Report an answer you believe is wrong or missing, so Fuentio checks it against the official source. Use it when a result contradicts an official document you hold. Don't use it to ask questions: call the lookup tools.

Description, as the server wrote it 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, and in France the public contracts won). Use it for the registry part of a KYB or supplier review you must file (not full KYB: no UBO, PEP or adverse-media checks). Don't use it for one quick fact: call lookup_company. Inputs: country and identifier, as lookup_company (e.g. 'FR', '441639465'). Returns: company, facts, links, decisions, changes_last_year, modules, gaps, uncertainty, sha256, markdown.

Returns: result 'possible_match' (list, entry, score, reasons, listing date, legal act, official link), 'no_match_found' or 'not_checked', the list versions, and a note. Limits: 2 units; API key required. A possible match is not proof; no match is never 'clear'. Read-only.
