Use when an agent must vet a company or counterparty before paying, onboarding or invoicing. Input: name, optional country (ISO2), lei, vat (EU, with prefix). Output: JSON summary (sanctions hits, LEI found/status, VAT valid), sanctions matches across OFAC SDN, EU and UK lists, GLEIF entity record with parents, VIES VAT result; a down VIES/GLEIF marks only that part. Not a legal determination. Example: ?name=Siemens+AG&lei=W38RGI023J3WT1HWRP32&vat=DE129273398
