How this service works
x402 endpoint checker: tests any paid x402 URL for a correct 402, price and networks, pay-to address, discovery metadata, CORS, response time and Coinbase's validator, and lists every issue to fix.
Output
Returns a detailed diagnostic report covering: whether the URL returns a valid 402 status, the declared price and supported networks, the pay-to address, discovery metadata, CORS configuration, response time, Coinbase validator pass/fail result, and a structured list of every compliance issue found that needs to be fixed.
Example use cases
Pre-launch x402 API audit
“Before I publish my paid API, check https://myapi.example.com/data for x402 compliance — I want to know if the 402 response is correct, what price and networks it reports, and whether it passes Coinbase's validator.”
Debugging a broken x402 integration
“My x402 endpoint at https://api.myservice.io/v1/search isn't accepting payments correctly — can you check it and list every issue with the 402 response, pay-to address, and CORS headers?”
Verifying a third-party x402 URL
“I want to call https://partner.example.com/premium-data but I'm not sure it's properly set up for x402 — can you check its 402 response, price, supported networks, and response time before I integrate it?”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/x402/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that an x402-enabled URL is correctly configured before integrating it as a payer, or before launching your own x402 endpoint. It is the go-to tool for x402 protocol compliance auditing, covering all key dimensions (402 status, pricing, networks, CORS, Coinbase validator) in a single call. Prefer this over manual inspection or general HTTP testing tools when x402-specific compliance is the concern.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Target URL does not return a 402 at all — reported as a critical issue
- Malformed URL input — validation error before request is made
- Target URL returns an unexpected HTTP error — reported with status code
- Coinbase validator API unavailable — partial results with validator section skipped
