How this service works
Paid MCP wrapping live x402 OFAC SDN and SHA-256 meters. USDC on Base (preferred) and Solana.
Output
Returns a ranked list of SDN list matches for the queried name or entity, each with a match confidence score, relevant SDN entry details (name, aliases, entity type, program), and a SHA-256 hash of the response for audit trail purposes.
Example use cases
Customer onboarding sanctions check
“Before we onboard this new customer, screen the name 'Ahmad Al-Rashidi' against the OFAC SDN list with a threshold of 0.8 — I need to know if there are any matches before we proceed.”
Crypto wallet counterparty screening
“I need to run a sanctions check on 'Banco Internacional de Comercio' before we process this wire — screen it against the OFAC SDN list with a 0.9 threshold and give me up to 3 matches.”
Vendor due diligence compliance
“We're onboarding a new vendor called 'Global Trade Solutions Ltd' — can you check if they or any close name match appears on the OFAC SDN list, using a threshold of 0.75 and returning up to 10 results?”

Use this endpoint when you need a pay-per-call, auditable OFAC SDN sanctions screen with SHA-256 hashing for compliance audit trails, paid programmatically in USDC via the x402 protocol — ideal for AI agents performing automated KYC/AML checks without a subscription, or when you need cryptographic proof of the query result.
Side effects
- Empty or ambiguous query string returns no results or low-confidence matches
- Threshold set too high may produce false negatives for variant spellings
- Threshold set too low may flood results with irrelevant partial matches
- Payment failure in USDC/x402 results in 402 HTTP error and no data returned
- Service unavailability on Vercel deployment returns 5xx errors
- Query exceeding character limits may be rejected
