What is an OFAC screening API?

An OFAC screening API is a programmatic interface that checks counterparties (wallets, names, countries) against OFAC's sanctions lists in real time. Instead of manually searching the SDN list, you call the API and get an instant yes/no result.

API vs manual screening

Manual screening: open the SDN list PDF, search for a name, interpret results. ~5 minutes per check. API screening: one HTTP call, sub-100ms, automated. The API approach is the only viable option for automated payments and AI agents.
