#canonical

Live project, people and release data from Launchpad, Canonical's open-source collaboration platform and the home of Ubuntu, via its public REST API. Launchpad is built around free-software projects, the teams that maintain them and the people in those teams. Get a project's profile — its title and summary, homepage, the licences it is released under, when it was registered and whether it tracks bugs, answers and translations on Launchpad. Resolve any Launchpad name to a person or a team, with its display name, whether it is a team, when it joined and its self-description. Pull a team's membership — the people and sub-teams that make up an open-source community. Get a project's released versions with their dates. Live, no key, nothing stored. Distinct from GitHub, GitLab, Codeberg and SourceForge forge APIs — this is Launchpad's project registry, its teams and its people. Perfect for open-source-directory, packaging, release-tracking and developer-community apps.

Normalize URLs to a canonical form so you can deduplicate, compare and clean them. The canonicalize endpoint lower-cases the scheme and host, drops the default port (80 for http, 443 for https), resolves ./ and ../ path segments and fixes percent-encoding using the standard WHATWG URL parser, then applies the cleanups you choose: strip marketing and analytics tracking parameters (all utm_* plus gclid, fbclid, msclkid, yclid, mc_eid and many more), sort the remaining query parameters into a stable order, optionally drop the #fragment, and add or remove the trailing slash. It returns the canonical URL, the fully parsed components and the exact list of changes it made. The compare endpoint canonicalizes two URLs and tells you whether they point to the same resource — perfect for catching duplicate links that differ only by tracking codes, casing, port or parameter order. Everything is computed locally with no network calls, so it is instant, private and safe. Ideal for crawlers and SEO tooling, link deduplication and analytics, cache keys, bookmarking and content pipelines. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This canonicalizes the URL string; it does not fetch it or follow redirects — for link previews and unshortening use a URL-unfurl API.
