How this service works
Six keyless pay-per-call tools for AI agents: OFAC SDN crypto-wallet screen, live DNS records lookup, SPF/DMARC/DKIM email-auth check, domain age/registrar (RDAP), email address MX verify and URL unshorten/redirect check. $0.01 per call: USDC on Base over x402, or USDC on Tempo over MPP. Also a remote MCP server at /mcp (x402).
Output
A JSON object containing the queried wallet address, a 'sanctioned' boolean, the OFAC list publish date, and a 'matches' array. Each match includes the entity name, SDN UID, SDN type (e.g. Entity, Individual), the OFAC programs it is listed under (e.g. DPRK3), and the asset type (e.g. ETH, BTC).
Example use cases
Pre-payment sanctions screening
“I'm about to send USDC to 0x1234abcd5678ef901234abcd5678ef901234abcd — can you check if that wallet is sanctioned by OFAC before I proceed?”
DeFi protocol compliance check
“Our platform needs to block sanctioned wallets. Screen this Solana address HN7cABqLq46Es1jh92dQQisAq662SmxELLLsHHe4YWrH against the OFAC SDN list right now.”
Bitcoin withdrawal screening
“A user requested a Bitcoin withdrawal to 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na — run an OFAC SDN check on that BTC address before we release the funds.”
Technical details
Endpoint
GEThttps://sdn-screen-x402.sdnscreen.workers.dev/v1/screen?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-call, no-signup OFAC SDN exact-match check for a single crypto wallet address across multiple chains (EVM, BTC, TRX, SOL, etc.) without maintaining an API key or subscription. Ideal for AI agents performing compliance checks inline with crypto payment flows using x402 micropayments on Base.
Side effects
- Missing 'address' query parameter returns an error response
- Invalid or malformed wallet address may return no matches rather than an error
- Payment failure via x402 (insufficient USDC balance or unsupported wallet) blocks the request
- OFAC list may have a publication lag — listPublishDate indicates currency of the data
- Non-standard address formats for exotic chains may not be recognized
