How this service works
Screen every address a single transaction touches. Collects the sender, recipient, token-transfer endpoints and token contracts of one transaction, then checks each against the known registry, seven sanctions lists (OFAC, UK, JP, UN, EU, CA, CH) and the ScamDB drainer database. Returns one verdict: block / review / clear. Much cheaper than a full fund-flow trace because nothing is expanded beyond the transaction itself.
Output
A single compliance verdict — block, review, or clear — along with which sanctions lists or scam databases triggered any matches, covering the sender, recipient, all token-transfer endpoints, and token contracts found within the specified transaction.
Example use cases
Pre-withdrawal compliance gate
“Before I release this crypto withdrawal, screen transaction 0xabc123...def456 on Ethereum to check if any address involved is on OFAC or other sanctions lists — give me a block, review, or clear verdict.”
Incoming payment risk check
“We just received a payment on the Polygon chain, tx hash 0x9f8e...1234 — can you screen it against all major sanctions lists and the ScamDB drainer database so I know if it's safe to accept?”
DeFi protocol transaction audit
“Audit this Arbitrum transaction 0xd3ad...beef for sanctions and scam exposure — flag any involved addresses that appear on OFAC, EU, UN, or other watchlists and tell me the final verdict.”
Technical details
Endpoint
GEThttps://chain-analyzer.com/api/v1/x402/tx/:hash/screen?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, low-cost compliance check on a single transaction without requiring full recursive fund-flow tracing. It is ideal as a real-time gate before processing payments, withdrawals, or DeFi interactions where you only need to know if the immediate counterparties in one tx are sanctioned or known bad actors — not their full transaction history.
Side effects
- Invalid or malformed transaction hash returns a 400 error
- Unsupported chain identifier returns an error indicating the chain is not available
- Transaction not yet confirmed or not found on-chain returns a 404 or pending status
- Network timeout if the chain RPC is slow
- Payment failure (insufficient USDC balance) blocks the request at the x402 payment layer
