How this service works
Read-only x402 seller audit, link health and quote verification. Pay per call in USDC on Base via x402.
Output
Returns a JSON array of results, one per submitted URL, each containing the original URL, its HTTP status code, and a verdict string (e.g. 'ok') indicating whether the link is healthy and the x402 quote is valid.
Example use cases
Pre-launch x402 marketplace audit
“Before I publish my x402 API marketplace listing, can you audit all 10 of these seller endpoint URLs and tell me which ones are healthy and which are broken or misconfigured?”
Routine seller link health monitoring
“Run a health check on these 20 x402 payment endpoint URLs I manage and flag any that aren't returning a 200 status so I know what needs fixing.”
Competitor quote verification
“I found 8 x402 seller links in the wild — can you verify that each one is live and returning valid quotes, and give me a pass/fail verdict for each?”
Technical details
Endpoint
POSThttps://agent-audit.agent-audit.workers.dev/v1/links?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to bulk-verify the reachability and x402 quote integrity of up to 25 seller URLs in a single call. It is purpose-built for the x402 pay-per-call ecosystem, making it the right choice over generic HTTP ping tools when you specifically care about x402 payment endpoint health. Prefer it for pre-publication audits, routine monitoring of x402 listings, or validating third-party seller links before integrating them into an agent workflow.
Side effects
- Submitting more than 25 URLs returns a validation error
- Malformed URLs in the array may cause individual result errors or skipped entries
- Downstream endpoint timeouts may produce non-200 status verdicts for healthy-but-slow services
- Payment failure (insufficient USDC balance on Base) prevents the call from executing
- Network errors reaching the Cloudflare Worker return HTTP 5xx
