How this service works
Payment integration check for 0.001 USDC; no external data lookup. Returns time, rail, network mode and free/paid capabilities. HTTP payment options can include Base, Polygon, Arbitrum and XDC; the challenge lists currently available networks for each transport. The receipt identifies the paid network and transaction. Business/professional use only. Terms: https://402rates.com/data-terms/
Output
Returns a pong message along with the current server timestamp and the name of the x402 payment rail that processed the $0.001 USDC payment, confirming the full round-trip payment flow succeeded.
Example use cases
Verify x402 integration before launch
“Before I ship my new x402-gated API, can you fire a test ping through the Compass payment rails and confirm I get a pong back with the rail name and server timestamp?”
Debug micropayment connectivity issue
“My x402 payments seem to be failing — can you hit the Compass ping endpoint and tell me if the payment goes through and what rail it confirms on the response?”
Monitor payment rail health in CI
“As part of our nightly checks, run the Compass paid ping and report back whether we got a valid pong, the server time, and which x402 rail was used.”
Technical details
Endpoint
GEThttps://api.402rates.com/v1/pingWhen to prefer
Use this endpoint when you need to verify that the x402 micropayment infrastructure is functioning end-to-end, particularly when diagnosing integration issues, running health checks in CI/CD pipelines, or confirming that a USDC wallet and payment rail are correctly wired up before using higher-stakes x402-gated endpoints.
Side effects
- Insufficient USDC balance causes payment to fail before the endpoint is reached
- x402 payment rail is degraded or offline, returning a 402 or 5xx error
- Malformed payment header results in rejection at the payment gateway
- Network timeout before pong is returned
- Unsupported payment method or wallet causes authorization failure
