How this service works
x402 endpoint validator, uptime probe, and crawled directory index of working x402 Bazaar APIs ($0.001 USDC) — Audits HTTP 402 PAYMENT-REQUIRED headers and returns verified working x402 services.
Output
Returns an x402 compliance audit report for the target URL including HTTP 402 header validity, Bazaar schema conformance, uptime status, and optionally a crawled directory index of live-verified working x402 Bazaar APIs with their endpoints and pricing.
Example use cases
Pre-launch x402 endpoint audit
“I just set up my new paid API endpoint at https://myservice.io/api/data and want to make sure it's properly implementing x402 before I list it — can you probe it with a GET request and tell me if the HTTP 402 headers and Bazaar schema are correct?”
Discover verified live x402 APIs
“I'm looking for working x402 APIs I can integrate into my agent — can you pull the live-probed directory index of verified Bazaar services so I can see what's available?”
Monitor x402 uptime for a paid API
“Can you check right now whether https://partner-api.dev/v1/endpoint is up and still responding correctly to x402 payment protocol requests using POST, and let me know if anything looks broken?”
Technical details
Endpoint
POSThttps://windtrapdata.dev/v1/reliability/probe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a specific HTTPS endpoint correctly implements the x402 HTTP 402 payment protocol and Bazaar schema, or when you want to discover a curated directory of live, working x402 APIs. It is the go-to tool for x402 ecosystem discovery and compliance auditing, especially useful before integrating a new paid API or listing your own service on Bazaar.
Side effects
- Target URL is unreachable or returns unexpected HTTP status — probe returns uptime failure
- Target endpoint does not implement x402 at all — returns non-compliance report
- Invalid or malformed target URL — returns validation error
- Target URL returns x402 headers with incorrect schema — returns partial compliance with error details
- Directory index unavailable if crawl data is stale or service is down
