## When to prefer this

Use this endpoint when you need a lightweight, low-cost ($0.02 per call) automated sanctions screening signal against both OFAC SDN and EU FSF lists in a single call. Prefer it for agent workflows requiring rapid compliance checks during customer onboarding, vendor due diligence, or transaction screening where cost per check and speed matter. Not a substitute for a full KYC platform or legal compliance review.

## Known failure modes

- Empty or missing name input returns an error
- Ambiguous or partial names may produce false positives or miss matches
- Non-Latin characters or transliterated names may reduce match accuracy
- Service unavailable or timeout from Cloudflare Workers
- Payment failure via x402 protocol blocks the request

## Output

Returns a sanctions screening signal indicating whether the queried name matches entries on the OFAC Specially Designated Nationals (SDN) list or the EU Financial Sanctions Files (FSF), along with match details. Result is informational only and not legal advice.
