lion_ofac_sanctions_screen
ActiveTool of LION - keyless attested data for AI agents
Keyless OFAC sanctions screening for crypto addresses - no API key, no signup, payment is the only gate. Pass a crypto address (?address=0x...) and get ONE structured JSON: sanctioned (bool), list, match, snapshot_as_of, total_sanctioned_addresses. Screens against the US Treasury OFAC SDN sanctioned digital-currency-address list (refreshed daily into a snapshot; the authoritative 80MB XML cannot be parsed live in an edge worker). A cryptographically-provable single-field sanctions check - Ed25519-attested (verify offline), a narrow VERIFIABLE niche, NOT a broad compliance suite. Address-level only, NO PII. $0.005 USDC on Base via x402. Informational; verify against the official OFAC SDN list for binding compliance. Not legal advice. [x402 paid tool: GET /api/x402/sanctions-screen-json?src=mcp returns the 402 challenge with the canonical payTo; price 0.005 USDC on Base eip155:8453.]
