How this service works
Checks an address against the OFAC SDN list of sanctioned digital-currency addresses. Built for compliance agents and bots that must screen counterparties before transacting. Direct-address match; list refreshed regularly. No API key required. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
Returns a match/no-match result indicating whether the queried blockchain address appears on the OFAC SDN digital currency address list, enabling the caller to decide whether transacting with that address would violate sanctions rules.
Example use cases

Technical details
Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/sanctionsWhen to prefer
Use this endpoint when you need fast, automated pre-transaction compliance screening of individual blockchain addresses against the OFAC SDN list. Ideal for compliance agents, payment bots, or DeFi applications that must verify counterparties before executing on-chain transactions. Prefer this over manual lookups or general KYC services when you specifically need OFAC digital-currency address matching at low cost ($0.01/call) without API key friction.
Side effects
- 402 Payment Required — must pay $0.01 USDC on Base (eip155:8453) and retry
- Invalid or malformed address format returns an error
- Address not found in list returns a clean/no-match result (not an error)
- Stale list data if refresh cycle has not yet picked up newly added addresses
- Network timeout or relay outage at api.relai.fi
