How this service works
Crypto address screening vs the FULL live OFAC SDN list, segmented by chain (bitcoin, evm, tron, +9 more) — EVM adds on-chain signals (contract, fresh wallet) → 0-100 risk score
Output
Returns a structured object with: the chain and address screened, a boolean `sanctioned` flag and `sanction_source` (OFAC SDN or null), a `risk_score` from 0–100 (100 = sanctioned), a heuristic `verdict` enum (BLOCKED, REVIEW, or NO_RED_FLAGS_FOUND), an array of `reasons` driving the verdict, flags for `is_contract` and `fresh_wallet`, the outbound `tx_count`, the block height `as_of_block`, and a disclaimer string.
Example use cases
Example prompt
“Before I send funds, can you screen the address 0xAbC123...def on Base for OFAC sanctions and on-chain risk — I want to know if it's blocked, under review, or has no red flags, plus the risk score?”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/address-screen/check/:chain/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, inexpensive ($0.02 USDC) compliance pre-check combining OFAC SDN list screening with heuristic on-chain signals (contract detection, fresh wallet flag, tx count, risk score) for Base or Ethereum addresses — especially before initiating payments or smart contract interactions where regulatory or fraud risk matters.
Side effects
- Invalid or malformed address returns an error or unexpected result
- Unsupported chain slug (anything other than 'base' or 'ethereum') causes a failure
- Address not checksummed — endpoint lowercases input but malformed hex may fail
- Payment failure (x402 micropayment not completed) blocks the response
- Temporarily stale data if the chain node is behind; check as_of_block for freshness
- Fresh or newly deployed contracts may lack enough on-chain history for reliable signals
