Current path for validation test
Output
A validation response confirming that the x402 payment-gated request succeeded. Indicates the HTTP flow, payment processing, and endpoint routing are functioning as expected.
Example use cases
Smoke-test x402 payment integration
“Run a quick GET request against the x402 validation endpoint and confirm it returns a success response after the micropayment goes through — I want to make sure my payment gating is wired up correctly.”
Agent health check for paid endpoints
“Before my agent starts calling production APIs, can you probe the x402 validation endpoint to verify it can handle the $0.01 USDC payment and get back a valid response?”
Debugging a failed x402 payment flow
“My x402 payment flow isn't behaving right — can you make a GET call to the validation endpoint and tell me exactly what response comes back so I can figure out where things are breaking?”
Technical details
Endpoint
GEThttps://x402endpoint-924155002144.us-west2.run.app/validation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402 micropayment flow is correctly configured and that a payment-gated GET endpoint will respond after a $0.01 USDC payment. Ideal for smoke testing, integration checks, or debugging x402-based agent payment pipelines before hitting production endpoints.
Side effects

- Invalid HTTP method used (only GET, HEAD, DELETE accepted) — returns 405 Method Not Allowed
- Endpoint temporarily unavailable — returns 503
- Malformed request schema — returns 400 Bad Request
