How this service works
Use when testing an x402 client end to end. Returns ok and the server time; costs one cent.
Output
Returns an HTTP 200 response with a JSON body containing an 'ok' status indicator and the current server time, confirming the paid x402 request completed successfully.
Example use cases
End-to-end x402 client validation
“Run a live paid ping against PaywallWatch to make sure my x402 client can successfully complete a real payment and get back an OK response — I want to confirm the whole flow works before I ship.”
Smoke test before production deployment
“Before I push this x402 integration to production, can you fire off a one-cent ping to PaywallWatch and tell me if we get an OK and a valid server timestamp back?”
Debugging a failing micropayment client
“My x402 payment client seems broken — can you make a test call to the PaywallWatch ping endpoint for one cent and show me exactly what response comes back so I can figure out what's going wrong?”
Technical details
Endpoint
GEThttps://api.paywallwatch.com/v1/ping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real, cheap, live end-to-end test of an x402 HTTP payment client implementation. It is ideal as a smoke test or integration check before calling more expensive paid APIs, or when debugging why an x402 client is failing to complete payments.
Side effects
- Payment failure if x402 client is misconfigured or lacks sufficient USDC balance
- HTTP 402 returned if payment headers are missing or malformed
- Network timeout if the endpoint is temporarily unreachable
- Invalid or missing x402 payment token causes rejection without processing
