How this service works
Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.
Output
Returns a JSON object confirming the echo of your input message, a boolean ok flag, the endpoint purpose label ('end_to_end_x402_client_test'), the UTC server time at execution, a paid_x402_endpoint flag, the product name, service name, tool name, a limitations array noting no external action is taken, and a generated_at timestamp.
Example use cases
Verify x402 client integration works
“Send the message 'integration check' to the KEVAREMESH x402 ping endpoint and confirm the payment went through and we got an echo back.”
Debug agent micropayment setup
“Run a diagnostic ping against the KEVAREMESH x402 client test with the message 'debug test' so I can verify my CDP wallet is correctly set up to pay for API calls.”
Smoke test before production deploy
“Before I launch my agent, can you hit the KEVAREMESH x402 client test endpoint with 'smoke test' and make sure it returns ok:true and a server timestamp?”
Technical details
Endpoint
POSThttps://kevaremesh-web.vercel.app/api/x402/x402-client-test-cdp-x402-client-test?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that your x402 payment client (especially CDP-based) is correctly configured and able to complete a real micropayment cycle. It is the lowest-cost, lowest-risk way to confirm end-to-end x402 connectivity before invoking more expensive or consequential paid endpoints. Prefer this over production endpoints for initial integration testing and ongoing health checks.
Side effects
- Payment not received or insufficient USDC balance — x402 gateway rejects request before processing
- Malformed message exceeding 500 characters — input validation error
- Network or Vercel cold-start timeout — no response or 5xx error
- Invalid x402 payment header — gateway returns 402 without processing
- Message field missing — may return error or empty echo depending on implementation
