{"service":"SanctionsScreen","version":"1.0.0","tagline":"OFAC SDN sanctions screening for a name, entity, or wallet, agent-callable.","description":"OFAC sanctions screening made agent-callable. One x402 call screens a name, entity, vessel, or crypto wallet against the US Treasury OFAC SDN (Specially Designated Nationals) list plus its alternate-names list, and returns a sanctioned yes/no with a confidence level (exact / strong / possible), every matched entry (SDN name, type, OFAC program, entity number), and the list size screened against. Token-subset matching handles name reordering (e.g. 'Vladimir Putin' vs the SDN 'PUTIN, Vladimir Vladimirovich'). The compliance / AML check that trading, payment, and onboarding agents need before touching a counterparty, served pay-per-call instead of scraped from a portal. $0.05 in USDC on Base via x402.
