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.

Live project, release and download data from SourceForge, the original open-source software forge and download host. Unlike a git forge, SourceForge is built around distributing release binaries to the world, so its signature data is who downloads what, from where. Get a project's profile — its name, summary, status, creation date, homepage, the categories it is filed under and its developer count. Pull the download statistics for a date range — the total, the daily series and the breakdown by operating system. See where in the world a project is downloaded, the per-country download counts that no git forge exposes. Get the project's best current release with its file, version, size and date, plus the recommended download for Windows, macOS and Linux. Live, no key, nothing stored. Distinct from GitHub, GitLab and Codeberg git-forge APIs and from package registries — this is SourceForge's project directory and its global download analytics. Perfect for software-directory, release-tracking, download-analytics and developer apps.

Live profile, ranking and challenge data from Codewars, the competitive-programming community where developers level up by solving "kata". Get a member's whole standing — honor points, overall rank as a Codewars kyu/dan grade with its score, the per-language ranks they hold, their clan, their global leaderboard position and how many kata they have completed and authored. Pull the paginated list of kata a member has solved with the languages they used, the kata a member has created with rank and popularity, or any code challenge in full — its category, difficulty, tags, available languages and community stats (total completed, attempts, stars and vote score). Live, no key, nothing stored. Distinct from Codeforces, GitHub and Stack Exchange APIs — this is the Codewars honor, kyu-rank, clan, leaderboard and kata-challenge graph. Perfect for developer leaderboards, coding-community, gamification, portfolio and recruiting apps.

Live profile and repository data from Codeberg as an API — the community-run, Forgejo-powered git host and a leading open-source alternative to GitHub. Look up any user or organisation for their profile and social reach (followers, following, starred repositories, join date, location and website), open any repository for its stats (stars, forks, watchers, open issues, primary language, size and dates), or search Codeberg's repositories ranked by stars. The git-forge community layer for developer, social and dashboard apps. Live, no key, no cache. Distinct from GitHub and GitLab APIs and from package-registry APIs — this is the Codeberg platform's own community and project data.

The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

Every top-level domain in the IANA root zone as an API — the authoritative list a registrar, domain validator or analytics tool needs. For each TLD: whether it is a country-code TLD (ccTLD), a generic TLD (gTLD) or an internationalized (IDN) domain, its A-label, its Unicode form (e.g. xn--p1ai resolves to .рф) and, for ccTLDs, the country it belongs to. Validate a TLD or whole domain, find a country's ccTLD, filter by type, search, or list the entire root zone. Sourced from IANA's official tlds-alpha-by-domain.txt and served from memory — always fast.

The ISO 15924 register of writing systems — the script codes used by Unicode, BCP-47 and CLDR — served from memory (no key). Every script carries its 4-letter code (e.g. Latn, Arab, Hani), numeric code, English and French names, the Unicode property value alias, the Unicode version it was added in and its date. Look a script up by code or numeric, search by code or name, or list the whole register. 226 scripts. Ideal for internationalization, locale and font tooling, BCP-47 tag validation and text-rendering pipelines.

The canonical MIME / media-type database (the jshttp mime-db used by Express and most of the Node ecosystem: IANA + Apache + nginx), served from memory — no key. Resolve a media type to its file extensions, charset and compressibility; reverse-lookup the media type(s) for a file extension (e.g. png → image/png); and search or list types by source. 2,600+ media types, 1,000+ with file extensions. Lean, predictable JSON. Ideal for upload validation, Content-Type resolution, file-type detection, download handlers and developer tooling.

IETF BCP 47 language tags (locales) as an API, built on the IANA Language Subtag Registry — 9,200+ subtags (languages, scripts, regions, variants, extlangs and grandfathered tags). The headline /parse endpoint validates and decomposes any language tag (e.g. zh-Hant-TW → Chinese + Han Traditional script + Taiwan; en-Latn-US, de-CH-1996, i-klingon) into its labelled subtags, flags invalid or deprecated parts, and recognises pre-registered redundant/grandfathered tags.

Detect human faces in an image and analyse each one with on-device machine learning: get the bounding box and a detection confidence, an estimated age, the predicted gender with its probability, and the dominant facial expression together with the full per-expression breakdown (neutral, happy, sad, angry, fearful, disgusted and surprised). A lightweight count endpoint returns just the number of faces and their boxes for fast gating. Supply an image by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked, and large images are downscaled automatically.

Catch spelling mistakes in six languages — English, German, Spanish, French, Portuguese and Dutch — and get English style and grammar suggestions in one call. Spelling errors come with their position in the text and a ranked list of corrections; style suggestions flag repeated words, weasel words, passive voice, wordiness, clichés and more. A combined check returns spelling and style together (sorted by position), a spelling-only endpoint covers all six languages, a single-word endpoint returns corrections for one word, and a languages endpoint lists what is supported. Every endpoint takes text via the query string or the request body and returns lean JSON.
