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, settledDelivery: true, an ISO 8601 timestamp, Unix milliseconds, a UUID request ID, and the echoed input string — confirming the payment was processed and the endpoint is reachable.
Example use cases
Validate x402 payment pipeline before deployment
“Before I launch my agent fleet, ping AgentResolver with echo 'pre-launch-check' so I can confirm the x402 USDC payment goes through and I get a settled delivery confirmation back.”
Debug a failing paid API integration
“I'm not sure if my x402 payment setup is broken or if AgentResolver is down — can you send a ping with echo 'debug-run' and tell me whether pong came back true and settledDelivery was confirmed?”
Latency baseline for x402 micropayment calls
“Run a ping to AgentResolver with echo 'latency-test' and give me the exact unixMs timestamp so I can measure how long the round-trip takes for a paid x402 request.”
Technical details
Endpoint
GEThttps://agentresolver.vercel.app/api/x402-pingWhen to prefer
Choose this endpoint when you need to verify end-to-end x402 micropayment connectivity specifically through AgentResolver, confirm that USDC settlement is working, or establish a latency baseline for paid agent API calls. It is the canonical health-check for the AgentResolver x402 payment pipeline.
Side effects
- Payment not settled — USDC balance insufficient, returns 402 Payment Required
- Invalid or missing x402 payment header — request rejected before processing
- Network timeout reaching agentresolver.vercel.app
- Malformed input — echo field is not a string, returns validation error
- Rate limiting or Vercel cold-start delay causing slow response
