How this service works
Agent risk score — deterministic 0–100 trust summary of a wallet's observed x402 payment behaviour (conformance certs + public chain facts). For sellers, wallets & marketplaces. Body: {"wallet":"0x…"}.
Output
Returns a JSON object with: transaction hash (tx), paid boolean confirming USDC settlement, order label, amount paid, network (Base), currency (USDC), a unique receipt number (AC-XXXXXX format), and a guestbook URL for on-chain verification.
Example use cases
Pre-payment wallet risk check
“Before my marketplace accepts payment from this AI agent at 0x9f3a...bc12, can you score its wallet risk on Base so I know whether to trust the transaction?”
Certify agent payment receipt
“My agent just paid 0.10 USDC on Base via x402 — can you verify the transaction 0xdeadbeef...cafe and give me the receipt number confirming it went through?”
Agent-to-agent deal escrow check
“I'm setting up an automated deal between two agents and need to confirm that the paying wallet 0x4e7f...99aa on Base has a safe payment risk score before we lock funds in escrow.”
Technical details
Endpoint
POSThttps://api.402.coffee/scoreWhen to prefer
Choose this endpoint when you need to assess payment risk for AI agent wallets specifically on the Base network using the x402 protocol with USDC — particularly when you need an on-chain verifiable receipt and trust certification rather than a generic crypto address lookup or off-chain credit scoring service.
Side effects
- Wallet address not found on Base — returns error with null score
- Insufficient USDC balance or failed x402 payment — paid: false with no receipt issued
- Invalid or malformed wallet address — validation error before scoring
- Network congestion on Base causing delayed transaction confirmation
- High-risk wallet flagged — score returned but certification denied
