How this service works
The trust layer for AI-agent payments on Base. One live x402 endpoint that certifies agents pay safely, scores any wallet's payment risk, and escrows agent deals with automated on-chain arbitration. Real USDC, verifiable on-chain.
Output
A batch risk score response for each submitted wallet address, indicating payment safety and trustworthiness on Base. Results are verifiable on-chain and denominated in the context of USDC payment behavior. The response includes a transaction hash, payment confirmation, and receipt details tied to the scoring call itself.
Example use cases
Pre-screening agents before a marketplace deal
“Before I accept payment from these three agent wallets — 0xAAA…, 0xBBB…, and 0xCCC… — can you run a batch risk score on them so I know which ones are safe to transact with on Base?”
Filtering risky wallets from a payment queue
“I have a queue of 15 wallet addresses that want to pay via USDC on Base — can you score all of them for payment risk at once so I can reject the sketchy ones before processing?”
Due diligence on new agent counterparties
“We're onboarding a fleet of AI agents and need to vet their wallets — can you run a batch risk assessment on these 8 addresses before we allow them to make any on-chain payments through our platform?”
Technical details
Endpoint
POSThttps://api.402.coffee/score/batchWhen to prefer
Choose this endpoint when you need to risk-score multiple wallets simultaneously (up to 25) in a single API call rather than scoring them one by one. It is purpose-built for AI agent payment trust on Base via the x402 protocol, making it ideal for agent marketplaces, payment gateways, or orchestration layers that need to vet counterparty wallets before committing to USDC transactions. Prefer this over generic blockchain analytics tools when you specifically need x402-native, Base-compatible risk signals with on-chain verifiability.
Side effects
- More than 25 wallets submitted — API rejects with validation error
- Invalid or malformed wallet address in the array — may cause partial or full failure
- Insufficient USDC balance to cover the $0.50 per-call fee — payment rejected
- Network congestion on Base causing delayed or failed on-chain settlement
- Empty wallets array submitted — returns validation error
