How this service works
Vet an entire payment before an agent sends money: is the counterparty site legit, is the payee wallet sanctioned or disposable, is the amount within policy. Returns proceed/caution/stop, reasons, and a signed attestation — one go/no-go instead of three calls. Input: ?domain=merchant.com&wallet=0x...&amount=500
Output
Returns a tri-state decision (proceed / caution / stop), a list of reasons explaining the verdict, a domain trust assessment (scam/fraud/phishing/rug-pull risk), a wallet status (OFAC-sanctioned or disposable flag), and a signed, verifiable attestation — all in a single response.
Example use cases
Pre-payment scam check for DeFi agent
“Before sending $200 to 0xDEAD...BEEF, run a safety check on the site uniswap-airdrop.io and that wallet — tell me if it's safe or a rug pull.”
OFAC compliance screen before contractor payout
“I'm about to pay a contractor $500 — can you verify that their domain freelancer-payments.io and wallet 0x1234...5678 aren't on any sanctions list before we proceed?”
Marketplace transaction vetting for shopping agent
“I want to buy from opensea-deals.net and pay to wallet 0xABCD...9876 for $150 — can you do a quick trust check on both the site and the wallet before I confirm?”
Technical details
Endpoint
GEThttps://agents.dyoeway.org/transaction?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a single pre-payment vetting call that simultaneously checks domain legitimacy (scam/phishing/rug) and wallet safety (OFAC sanctions) before executing a transaction — instead of making three separate calls to a fraud API, a domain reputation API, and a sanctions screening API. Best for agentic payment flows where speed and a signed, verifiable attestation matter.
Side effects
- Invalid or malformed wallet address returns an error or low-confidence result
- Domain not resolvable or newly registered may return limited trust data
- OFAC database lookup delays could cause timeouts
- Missing required parameters (domain, wallet) returns a 400-level error
- Payment of $0.10 USDC not sent correctly results in 402 Payment Required
