How this service works
x402 test endpoint — live x402 test endpoint for testing an x402 client: the smallest possible paid round-trip that proves challenge parsing, USDC signing, facilitator settlement and retry. Use it to test x402 payments end to end before pointing a client at a real paid API. Returns pong + network + server time. No API key.
Output
Returns a JSON object containing a pong acknowledgement, the network identifier, and the current server timestamp — confirming that the full x402 paid round-trip (challenge parsing, USDC signing, facilitator settlement, and retry) completed successfully.
Example use cases
Smoke-test new x402 client library
“I just finished building an x402 payment client — can you hit the x402 testbed ping endpoint to confirm it successfully parses the 402 challenge, signs with USDC, settles through the facilitator, and gets back a pong?”
CI gate for micropayment integration
“Before we deploy, run a live check against the x402 testbed ping so we know the full payment round-trip — challenge parsing, USDC signing, and facilitator settlement — is working in this environment.”
Debug facilitator settlement issues
“My x402 payments are failing at the settlement step — can you test against the x402 testbed ping endpoint and tell me the exact response you get back, including the network and server time, so I can pinpoint where it's breaking?”
Technical details
Endpoint
GEThttps://health-api.tail11a58f.ts.net/ping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate an x402 micropayment client implementation end-to-end — including challenge parsing, USDC signing, and facilitator settlement — before connecting to a real paid API. It is the lowest-cost ($0.001 USDC) and lowest-risk way to prove the full payment stack works. Prefer it over production APIs during development, CI pipelines, or debugging payment failures.
Side effects
- Payment challenge not handled: client returns 402 without completing the payment flow
- Invalid USDC signature: facilitator rejects the payment and returns an error
- Facilitator settlement timeout: payment submitted but not confirmed in time
- Network mismatch: USDC sent on wrong chain rejected by facilitator
- Insufficient USDC balance: wallet cannot cover the $0.001 micropayment
