How this service works
Find out why an x402 endpoint isn't listed in the Coinbase CDP Bazaar: checks CDP's live index status and can make a real test payment.
Output
Returns the CDP Bazaar index status for the given x402 endpoint, including reasons why it may not be listed, along with an optional real payment test result showing whether the payment flow is functional end-to-end.
Example use cases
Debugging missing bazaar listing
“My x402 POST endpoint at https://api.example.com/transcribe isn't appearing in the Coinbase CDP Bazaar — can you diagnose what's wrong with it and send its example request body so we can confirm it's reachable?”
Confirming new endpoint is indexed
“I just deployed a new x402 GET endpoint at https://tools.myapp.io/summarize — can you check whether it's live in the CDP index and make a real test payment to confirm the full payment flow works?”
Marketplace readiness check before launch
“Before I announce my x402 API at https://beta.aiservice.dev/classify to developers, can you run a full diagnosis to see if it's properly listed in the Coinbase bazaar and whether payments go through?”
Technical details
Endpoint
POSThttps://unlisted.sh/diagnose?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have an x402-protected API that is not appearing in the Coinbase CDP Bazaar and need to understand why. It is the purpose-built diagnostic tool for x402 listing issues, combining live CDP index checks with optional real payment testing in a single call — no manual curl or separate payment testing needed.
Side effects
- Target URL is unreachable or returns non-402 status — diagnosis cannot determine listing issues
- Invalid or malformed URL input — returns validation error
- Target endpoint rejects test payment — payment failure details returned
- CDP index temporarily unavailable — may return incomplete status
- Incorrect HTTP method specified — diagnosis may return misleading results
