How this service works
x402 developer tool. Use to find out whether an x402 seller is listed in Coinbase CDP Bazaar and, if not, why. GET with required url (host or https URL). Reads CDP discovery and the host's /.well-known/x402, then sends one unpaid request per route; never pays. Returns JSON: verdict, per-route indexed status and networks (Base, Solana), and fail/warn findings each with a fix line. https only; private targets blocked. Errors are not charged.
Output
A JSON object containing a verdict (listed or not), per-route indexed status with supported networks (Base, Solana), and a list of fail and warn findings each accompanied by a specific fix line explaining what to correct.
Example use cases
Diagnosing a missing Bazaar listing
“My x402 API at payments.myservice.com isn't showing up in Coinbase CDP Bazaar — can you run a Bazaar check on it and tell me what's blocking it and how to fix each issue?”
Verifying x402 well-known config
“I just set up my /.well-known/x402 file on https://api.startupxyz.io — can you check if it's configured correctly for Bazaar discovery and flag any warnings?”
Confirming Base and Solana network support
“Before I publish my x402 seller listing, can you check https://checkout.myapp.dev/api/pay to confirm it properly advertises Base and Solana network support for Bazaar?”
Technical details
Endpoint
GEThttps://horizonpulse.dev/api/bazaar-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to debug why an x402 seller is absent from Coinbase CDP Bazaar, get a structured per-route breakdown of x402 configuration issues, or receive actionable fix guidance before or after publishing a listing. It is the purpose-built diagnostic tool for x402/Bazaar compliance — prefer it over generic HTTP probing tools when the goal is specifically Bazaar discoverability and x402 protocol conformance.
Side effects
- Private or localhost targets are blocked and return an error
- Non-https URLs are rejected
- Unreachable hosts return a connectivity error
- Missing or malformed /.well-known/x402 results in fail findings rather than a hard error
- Rate limiting or upstream CDP discovery outages may cause transient failures
