How this service works
Paid MCP wrapping live x402 OFAC SDN and SHA-256 meters. USDC on Base (preferred) and Solana.
Output
Returns a list of SDN matches for the queried name or entity, each with a similarity/confidence score, the matched name on the SDN list, and associated sanctions metadata such as entity type, program, and identifiers — capped by the specified limit and filtered by the specified threshold.
Example use cases
Customer onboarding sanctions check
“Before we onboard this new customer, can you screen the name 'Hassan Al-Rashidi' against the OFAC SDN list with a threshold of 0.8 and a limit of 10 results so I know if there are any sanctions hits?”
Crypto transaction counterparty screening
“I'm about to send crypto to a counterparty called 'Mahan Air' — can you run a sanctions check against the OFAC SDN list with an 0.9 threshold to make sure they're not blocked?”
Third-party vendor compliance check
“We need to verify a vendor named 'Rosoboronexport' before signing a contract — please search them on the OFAC SDN list with a match threshold of 0.85 and show me up to 5 results.”

Endpoint
POSThttps://x402-paid-mcp.vercel.app/api/v1/ofac-sdn?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need live, pay-per-call OFAC SDN screening without standing up your own compliance infrastructure, especially in crypto-native or Web3 workflows where USDC micropayments via x402 are natural. It is well-suited for agent-driven AML/KYC flows, transaction screening pipelines, or onboarding checks where you want fuzzy matching with a configurable threshold rather than exact-match only.
Side effects
- Query string missing or empty — returns validation error
- Threshold out of valid range — may return error or unfiltered results
- Payment not completed (x402 protocol) — returns 402 Payment Required
- OFAC SDN data source temporarily unavailable — returns upstream error
- No matches found above threshold — returns empty results list
