Try the free checker Get an API keyDevelopers building payment agents need compliance that does not slow them down. agentmail is a one-call OFAC sanctions screen: pass a wallet address, name, or country code, get back a clean or flagged result in under 100ms. No SDK to install, no webhook to configure, no enterprise sales call.
The API screens against 782 OFAC-sanctioned crypto wallets across ETH, BTC, USDT, and Tron, plus 19,086 sanctioned names and 16 embargoed jurisdictions. Data is sourced from the US Treasury OFAC SDN list and vile/ofac-sdn-list, refreshed daily. Fuzzy matching catches name variations and entity aliases. Every screen is logged with a timestamp for audit purposes.
