How this service works
Machine-callable x402-paid utilities for autonomous agents.
Output
Returns a JSON array of per-URL results, each containing: ok (boolean), url (original), broken (boolean), status (HTTP code), final_url (after redirects), redirects (count), error_code, and latency_ms. Also returns aggregate counts: broken, healthy, checked, plus a timestamp and version.
Example use cases
Pre-publish content link audit
“Before I publish this article, check all these outbound links for me and tell me which ones are dead or redirecting somewhere unexpected: https://source1.com/article, https://source2.com/study, https://source3.com/data”
Sitemap health check
“Here are 15 URLs from my sitemap — can you scan all of them and flag any that aren't returning a 200 so I can fix them before Google recrawls?”
Newsletter link verification
“I'm about to send my email newsletter — please verify that all the links in it are working: https://mysite.com/offer, https://mysite.com/unsubscribe, https://partner.com/promo, and let me know if any are broken or redirecting.”
Technical details
Endpoint
POSThttps://creator-desk-x402-isolated.onrender.com/v1/web/broken-links?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify the reachability of a known list of up to 20 URLs at once, especially in automated content pipelines, pre-publish audits, or SEO workflows. It is ideal for agents that already have a concrete list of URLs to check rather than needing to crawl or discover links. Prefer this over a full site crawler when the URL list is bounded and explicit.
Side effects
- Private/localhost URLs or non-port-443 targets are rejected with an error
- URLs returning connection timeouts will be flagged as broken with a null status
- Invalid URL formats will be rejected at input validation
- Non-HTTPS URLs are rejected
- Batch limit of 20 URLs exceeded returns a validation error
- Sites with aggressive bot-blocking may return misleading non-error status codes
