Redirect Chain Checker API

Network tool

POST https://api.findutils.com/api/tools/redirect-chain-checker/execute

Follow the redirect chain of a public http(s) URL hop by hop and return each hop's URL, HTTP status, Location and time in milliseconds, plus the final URL and the number of hops. Requests use HEAD (GET only when HEAD is refused), follow at most 10 hops, detect loops, refuse any hop to a private, loopback, link-local or local address, and check the final HTML page for a meta refresh by reading at most 16 KB of it.
