How this service works
Small pay-per-call utility APIs for AI agents. Pay per request in USDC on Base via x402 (v2, exact scheme). No accounts, no API keys.
Output
Returns a JSON object with: the sanctions list build timestamp and total address count, per-address results listing any matching sanctioned entity names, asset types (e.g. ETH, BTC), and program codes (e.g. CYBER2), plus a boolean anySanctioned field indicating whether any of the queried addresses are sanctioned.
Example use cases
Pre-transfer compliance check
“I'm about to send USDC to 0x252a8bd2319d8a555b872990601221b3a2053bce — can you verify it's not on the OFAC sanctions list before I proceed?”
Batch screening of counterparties
“We received deposits from these five wallet addresses: 0xABC…, 0xDEF…, 0x123…, 0x456…, 0x789… — can you screen all of them against the OFAC sanctions list at once?”
DeFi protocol onboarding check
“Before we whitelist this new liquidity provider wallet 0x1234567890abcdef1234567890abcdef12345678, check if it shows up anywhere on the OFAC crypto sanctions database.”
Technical details
Endpoint
GEThttps://agent-utils-x402-production.revenue-agent-jw.workers.dev/v1/sanctions/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call OFAC sanctions screen for crypto wallet addresses with no API key or account setup required. It is ideal for AI agents that need occasional compliance checks without committing to a subscription service. Prefer this over full KYC/AML platforms when you only need address-level sanctions screening rather than identity verification or full transaction monitoring.
Side effects
- Missing or invalid address query param returns 400 error
- More than 20 comma-separated addresses in a single request may be rejected
- Payment failure via x402 protocol prevents request from completing
- Malformed address strings may return no match rather than an error
- Stale sanctions list if list build timestamp is old (builtAt field should be checked)
