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 structured diagnostic report covering: whether the URL returns a proper HTTP 402 status, the detected price and accepted networks, the pay-to address, discovery metadata fields, CORS header correctness, measured response time, Coinbase validator pass/fail result, and an itemized list of every issue detected that needs to be fixed.
Example use cases
Debug a broken x402 payment gate
“My x402 endpoint at https://api.myservice.com/premium/data isn't working — can you check whether it's returning a proper 402 response, has the right price and network configured, and list everything that needs fixing?”
Pre-launch x402 compliance audit
“Before I go live, can you audit https://beta.myapp.io/v1/report for x402 compliance — I need to know if the pay-to address, discovery metadata, CORS, and Coinbase validator are all good to go?”
Verify Coinbase validator approval
“Can you test https://tools.devplatform.com/api/generate against the Coinbase validator and tell me if there are any x402 issues with the 402 status, price, or supported networks?”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/x402/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically validate an x402-protocol paid API endpoint for spec compliance, Coinbase validator approval, and deployment readiness. It is purpose-built for x402 diagnostics unlike generic HTTP checkers or uptime monitors that lack payment protocol awareness.
Side effects
- Target URL is unreachable or returns a non-402 response — reported as a compliance failure
- URL does not implement x402 at all — checker reports missing required fields
- CORS misconfiguration detected and reported in issues list
- Coinbase validator rejects the endpoint — failure reason included in results
- Malformed pay-to address or unsupported network — flagged in issues
- Slow response time exceeding acceptable thresholds — flagged as a warning
