How this service works
Sanctions screen for one crypto address, for agents and apps that send payments: exact match against all 1050 digital currency addresses in the official US Treasury OFAC SDN list (EVM case-insensitive). Returns sanctioned true/false, matching SDN entity, programs and list date, a chain guess and checksum validity, plus the list date. Informational, not legal advice.
Output
Returns a JSON object with: a boolean 'sanctioned' field, the matching SDN entity name (if any), the OFAC programs associated with the match, the date the address was added to the SDN list, a best-guess blockchain/chain identifier, and a checksum validity flag for the address format.
Example use cases
Pre-payment sanctions compliance check
“I'm about to send USDC to 0x3a1b2c3d4e5f6789abcdef012345678901234567 — can you run it through the OFAC SDN list first and tell me if it's sanctioned or safe to pay?”
DeFi protocol wallet screening
“We need to screen this user's Ethereum address 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 before allowing them to interact with our DeFi protocol — check if it appears on the OFAC SDN sanctions list.”
Bitcoin address sanctions lookup
“Can you check if this Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na is on the US Treasury OFAC blacklist, and if so, tell me which SDN entity it belongs to?”
Technical details
Endpoint
GEThttps://payguard.agentgate.workers.dev/v1/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or payment application needs to perform a quick, low-cost OFAC SDN sanctions check on a single cryptocurrency address before initiating a transfer. It covers all 1050 digital currency addresses on the official US Treasury SDN list with EVM case-insensitive matching, and supports multiple chains including EVM, BTC, TRX, SOL, LTC, and XMR. Prefer this over manual list lookups or heavyweight compliance APIs when you need a lightweight, per-call micro-priced check integrated directly into an agent payment workflow.
Side effects
- Missing 'address' query parameter — returns 400 error
- Invalid or unrecognizable address format — returns chain guess as unknown with checksum invalid
- Address not found on SDN list — returns sanctioned: false with no entity details
- OFAC list data may lag real-time Treasury updates — list date field indicates freshness
- Payment failure for the $0.001 USDC x402 fee — request blocked before screening
