      summary: 'Company identity: name, domain, LEI, VAT, CIK or ticker to one verified legal…'
      description: 'Resolves a company name, web domain, LEI, EU VAT number, SEC CIK or stock ticker to one legal entity using official free registries in a single call: GLEIF (legal name, other names, addresses, jurisdiction, registry id, direct and ultimate parent), the SEC ticker table (CIK, ticker), the EU VIES VAT service, and Companies House officers when the operator has configured a key. Deterministic matching with explicit ambiguity: when no single candidate clearly leads, it returns status "ambiguous" with ranked candidates instead of guessing. For KYC, vendor onboarding and CRM de-duplication by agents. It does NOT fetch or scrape the domain, does not cover companies without an LEI, does not return beneficial owners or financials, and uses no model.
