Use when an AI agent or treasury is about to pay, receive from or interact with a crypto wallet: checks the address against the US OFAC SDN sanctions list (all its digital-currency addresses: ETH/EVM, BTC, TRX, SOL, USDT, USDC…) and returns sanctioned true/false, the listed entity and programs, and the exact list version used, with a signed receipt. Errors: 400 invalid address (not charged); 503 if no sanctions list is loaded (not charged).
