Frequently asked questions

What is the URL Redirect Checker API?

The Agenty Redirects API traces the complete redirect path for any URL. It records every hop, HTTP status code, response time, and final destination, helping you detect loops and long chains. See the API reference for the full response.

How many hops can it trace?

Up to 20 hops. Each hop includes its status code, response time, and the location it redirects to. To check many URLs, paste them into the tool above and download every hop as CSV. To find the URLs to check, use the link extractor.

Can I check redirects as a specific user agent?

Yes. Pass a userAgent string to simulate mobile browsers, crawlers like Googlebot, or custom clients — some sites serve different redirects based on the user agent.

Does it detect redirect loops?

Yes. We detect circular redirects and flag them in the response. A loop is reported when a URL redirects back to one already seen in the chain.

Is there a free tier?

Yes. All accounts include free credits. See our pricing page for details.
