How this service works
Wallet-risk check before paying any wallet: OFAC sanctions screening, whether it's a monitored x402 seller's payout wallet and how long it's been stable, recent unconfirmed payout-wallet switches to it (possible hijack), seller declarations, x402 payment history, and on-chain intelligence (first funder, one step back, wallet age and activity). Add compare=<other wallet> for same-owner evidence and a 0-1 confidence. Verdict: clear, caution, or block.
Output
Returns a JSON object with the wallet address, a plain-language verdict ('clear', 'flagged', etc.), an array of human-readable reasons explaining the verdict (e.g. stable payout history, associated seller domains), and a sanctions object showing whether the wallet was screened, whether it's on a sanctions list, and any relevant list date.
Example use cases
Pre-payment sanctions screen
“Before my agent pays this API, check whether the payout wallet 0x4a8F…3c21 is sanctioned or flagged — I don't want to send money to a blocked address.”
Payout wallet change detection
“The API I've been paying just changed its payout wallet to 0xB9d1…77Ae. Can you compare it against the old wallet 0x23Fa…90Cc and tell me if they seem to be the same owner, or if something suspicious is going on?”
New vendor wallet vetting
“I'm about to let my agent start paying a new x402 vendor at 0xC3eA…12Fb. Can you run a full risk and sanctions check on their wallet first and tell me whether it looks legitimate?”
Technical details
Endpoint
GEThttps://lumierepaycheck.org/v1/wallet-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a fast, lightweight pre-payment wallet check — specifically verifying sanctions status and payout legitimacy before executing an x402 micropayment. Prefer this over a full trust report endpoint when you only need the wallet verdict and don't require endpoint scoring, price history, or a complete audit trail. Ideal for inline agent workflows where a go/no-go decision on a wallet is needed in real time before funds are sent.
Side effects
- Missing required 'address' query parameter returns an error
- Invalid wallet address format (neither valid EVM 0x… nor Solana address) returns an error
- Address not yet seen in any x402 payout context may return limited or inconclusive reasons
- Sanctions data may have a freshness lag if upstream lists are not yet updated
- Compare address not recognized may reduce confidence in same-owner analysis
