How this service works
Check whether a list of URLs, or every link on a page, works: HTTP status, final URL after redirects and broken links first. Up to 50 URLs per call, checked in parallel.
Output
Returns a JSON object with the total number of links found on the page (if page mode), the number of URLs checked, the number broken, and a results array where each entry contains the original URL, a boolean ok flag, the HTTP status code, and the final URL after any redirects.
Example use cases
Website audit before launch
“Before we go live, can you scan https://staging.acmecorp.com/docs and find any broken links — I need to know the status code and final URL for each one that fails.”
Bulk URL health check
“I have this list of URLs I want to verify are all working: https://example.com/page1, https://example.com/old-post, https://partner.com/landing — can you check them all and flag any that are broken or redirect somewhere unexpected?”
SEO broken link monitoring
“Check all the links on https://myblog.com/sitemap-page for broken or redirecting URLs so I can fix them before they hurt my SEO — show me the status code and final destination for each.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/broken-links?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate the liveness and redirect behavior of multiple URLs simultaneously, especially when crawling a page to find all broken links automatically. Prefer this over single-URL HTTP checks when batch efficiency matters, or when you want the final resolved URL after redirect chains. Best suited for web QA, SEO audits, and content maintenance workflows.
Side effects
- Invalid or unreachable page URL returns an error with no results
- Exceeding 50 URLs per call may result in truncation or rejection
- Slow-responding target servers may cause timeouts for individual URLs
- Malformed URLs in the input list return error entries in the results array
- Private or firewalled URLs inaccessible from the checker's network will appear broken
