How this service works
No-body $0.001 x402 settlement test for funded agents. Verifies the buyer wallet, facilitator, USDC payment path, and paid delivery end-to-end by returning a timestamped pong only after successful settlement.
Output
Returns a JSON object with `pong: true` and `settledDelivery: true` only after the USDC micropayment has been successfully settled on-chain. Also echoes back any optional text provided via the `echo` query parameter, and includes a timestamp confirming the moment of paid delivery.
Example use cases
Pre-deployment x402 payment smoke test
“Before I launch my agent, run a live x402 canary settlement against the AgentResolver test endpoint to confirm my CDP wallet, facilitator, and USDC payment path all work end-to-end. Echo back 'deploy-ready' in the response so I can verify paid delivery.”
CI pipeline payment health check
“As part of my automated CI run, fire a $0.002 x402 canary settlement test and confirm I get a pong with settledDelivery true — fail the build if the payment or delivery doesn't complete successfully.”
Diagnosing a broken agent payment flow
“My agent is failing to receive paid API responses — can you run the x402 CDP canary test to check whether the problem is the wallet, the facilitator, or the USDC settlement step? Echo 'debug-run' so I can trace which stage succeeded.”
Technical details
Endpoint
GEThttps://agentresolver.vercel.app/api/x402-cdp-canary?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a complete x402 micropayment stack — including buyer wallet, USDC balance, facilitator routing, and paid content delivery — works correctly end-to-end. It is the canonical canary/smoke-test for x402 CDP agents, costing only $0.002 USDC per call. Prefer this over preflight-only checks when you need to confirm actual settlement and paid delivery, not just payment requirements.
Side effects
- Insufficient USDC balance in buyer wallet — payment rejected before settlement
- Invalid or misconfigured facilitator — settlement fails with payment error
- Wallet not funded or not on correct network — 402 Payment Required returned without delivery
- Echo parameter exceeds 256 characters — request rejected
- Network congestion or blockchain latency — settlement timeout
- TLS or endpoint verification failure — connection refused
