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: total URLs checked, total links found (if crawling a page), number of broken links, and a per-URL results array. Each result includes the original URL, final URL after any redirects, HTTP status code, and a boolean indicating whether the link is working.
Example use cases
Blog post link audit
“I just published a long blog post at https://mysite.com/ultimate-guide — can you scan all the outbound links and tell me which ones are broken or returning errors?”
Batch URL health check before launch
“Before we go live, check these 10 URLs for me and make sure they all return 200 and aren't redirecting to unexpected places: https://example.com/page1, https://example.com/page2, https://example.com/page3, https://example.com/page4, https://example.com/page5, https://example.com/page6, https://example.com/page7, https://example.com/page8, https://example.com/page9, https://example.com/page10”
Competitor site dead link discovery
“Can you crawl all the links on https://competitor.com/resources and give me a list of any broken ones — I want to see what's returning 404 or erroring out?”
Technical details
Endpoint
POSThttps://api.vextorium.com/comprobar-enlaces-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to batch-validate up to 50 URLs in parallel with redirect tracking, or when you want to automatically extract and check every link on a given web page. Ideal for site audits, pre-launch checks, or content freshness monitoring. Prefer this over single-URL checkers when you need bulk parallel checking with redirect chain resolution in a single API call.
Side effects
- Invalid or unreachable page URL returns empty results or error
- Exceeding 50 URL limit causes request to be capped or rejected
- Slow target servers may cause timeouts on individual URLs
- Malformed URLs in the input list may return null entries
- If neither urls nor pagina is provided, no links are checked
