The canonicalize endpoint lower-cases the scheme and host, removes the default port (80/443), resolves ./ and ../ path segments and fixes percent-encoding (all via the WHATWG URL parser), then applies the cleanups you want: strip marketing/analytics tracking parameters (utm_*, gclid, fbclid, msclkid and many more), sort the remaining query parameters, optionally drop the #fragment, and add or remove the trailing slash. It returns the canonical URL, the parsed components and exactly which changes were made. The compare endpoint canonicalizes two URLs and tells you whether they point to the same resource. Pure local, no network, no key."
