How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.
Output
A JSON object containing: the OFAC SDN list date used for screening, the screening method (exact address match), per-address results with match boolean, match type (exact_address or none), any SDN entity hits (including entity name, UID, type, chain, address, and sanctions programs), total match count, snapshot age in hours, source URL, and a compliance disclaimer. Addresses are normalized before comparison (0x and bech32 case-insensitive, base58 case-sensitive).
Example use cases
Pre-payment compliance check for DeFi protocol
“Before our smart contract releases funds to these three recipient wallets — 0x098B716B8Aaf21512996dC57EB0615e2383E2f96, 0xAbc123...def, and bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — can you screen them all against the OFAC SDN list to make sure none are sanctioned?”
Agent economy payer screening
“I need to verify that the wallets that paid into our x402 service today aren't on the OFAC SDN list — here are the 10 addresses from today's transactions, please batch-check them all.”
On-chain KYC before NFT airdrop
“We're about to airdrop tokens to 20 wallet addresses from our allowlist — can you run all of them through OFAC SDN screening so we don't accidentally send to a sanctioned party?”
Technical details
Endpoint
POSThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/sanctions/check/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, batch crypto address screening specifically against the OFAC SDN list as part of an automated compliance workflow, pre-payment check, or on-chain transaction gate. It is particularly well-suited for AI agents, DeFi protocols, and Web3 payment processors that need machine-readable sanctions verdicts for multiple addresses at once without manual lookup. Do not use it as a substitute for full legal compliance review, for non-SDN sanctions lists, or for screening by name rather than address.
Side effects
- Address string shorter than 20 or longer than 128 characters returns a validation error
- Batch exceeds 25 addresses — request is rejected
- Non-address inputs (e.g. ENS names or human-readable names) are not screened and will not match
- OFAC SDN list snapshot may be up to hours old — real-time changes won't be reflected immediately
- Only the SDN list is checked; OFAC non-SDN Consolidated lists and non-US sanctions lists are not covered
- A 'no match' result does not legally clear a counterparty — human review required for compliance decisions
