OFAC Sanctions Screening for Fintech Startups

By agentmail team · 2026-07-18

Answer: Fintech Startups agents screen counterparties against the OFAC SDN list (19,086 names, 782 crypto wallets, 16 embargoed jurisdictions) via a single API call before every payment. A "clean": true response means proceed; "clean": false means halt. The check runs in under 100ms and the free tier covers 5 checks/day with no API key.

Why do Fintech Startups agents need OFAC sanctions screening?

Fintech startups need OFAC sanctions screening from day one, but enterprise compliance vendors require annual contracts and sales calls. agentmail's free public API lets a startup ship sanctions checks in an afternoon.

Regulators expect sanctions screening proportional to your business. Starting with a real API call per transaction is defensible; starting with nothing is not. agentmail gives you the defensible baseline for free.

5 checks/day free, no API key. Scale to production from $19/mo when volume picks up. No enterprise contract required.
