How this service works
Screen an EVM wallet or contract address BEFORE paying it. Deterministic, keyless compliance / safety gate: checks the address against the OFAC sanctioned crypto-address list and a curated taint set (mixer, hack, scam) and returns a single BLOCK / REVIEW / ALLOW recommendation plus the matched sources, so an AI agent can decide whether to send funds. No API keys, no LLM, one x402 USDC micropayment per call.
Output
Returns a JSON object containing: a top-level recommendation (BLOCK, REVIEW, or ALLOW), a risk level (blocked/caution/clear) with reasons array, a sanctioned object (hit boolean, source, program), a taint object (hit boolean, categories array, label), the list of checked_lists, the as_of date of the last list refresh, the queried address and chain, and a disclaimer string.
Example use cases
Pre-payment compliance gate for DeFi agent
“I'm about to send USDC to 0xAb5801a7D398351b8bE11C439e05C5B3259aec9B — can you screen that address for OFAC sanctions and taint before I confirm the transfer?”
Smart contract safety check before interaction
“We're integrating with a new protocol contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on Ethereum — can you run a sanctions and taint check on it so I know it's safe to call?”
Automated payout screening for payroll agent
“I need to pay a vendor at 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD on Arbitrum — please screen that address against OFAC and mixer/scam lists and give me a clear BLOCK, REVIEW, or ALLOW before we proceed.”
Technical details
Endpoint
GEThttps://sanctions.cyberwarex.com/screen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, keyless compliance check on an EVM address before executing a payment or interacting with a contract. It is purpose-built for pre-payment safety gates in AI agent workflows and does not require API key management. Prefer it over general blockchain analytics APIs when you need a simple BLOCK/REVIEW/ALLOW signal from OFAC + mixer/hack/scam taint in a single call at very low cost ($0.005 USDC per check).
Side effects
- Invalid address format (not 0x + 40 hex chars) returns validation error
- Payment not received or micropayment fails — request blocked at x402 gate
- Address not found on any list — returns ALLOW with empty hit fields
- Stale list data if refresh has not occurred recently — as_of date indicates currency
- Unknown chain enum value provided — rejected by schema validation
