Codewars API

healthy 3,130 Subscribers

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.

LeetCode API

Live data from LeetCode, the largest coding-interview and competitive-programming community: a member's coding profile (global ranking, reputation, country, problems solved split by easy/medium/hard, total submissions and badges), their competitive standing (contest rating, global ranking, contests attended, top percentage), their activity (current solving streak, total active days, submissions over the past year) and LeetCode's daily coding challenge (today's problem, difficulty, acceptance rate and topic tags).

Launchpad API

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.

SourceForge API

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.

Inflector API

English word inflection as an API. Pluralize or singularize any word — correctly handling the irregulars that trip up naive code (person ↔ people, cactus ↔ cacti, goose ↔ geese, analysis ↔ analyses, and uncountables like sheep and series). Get count-aware inflection ("1 item" vs "3 items", optionally with the number included), and check whether a given word is already singular or plural. Everything is computed locally, so it is instant and always available. Ideal for ORMs and code generators, REST resource naming, UI labels and notifications ("3 result(s)"), search and autocomplete, and any app that turns counts into correct grammar. For case styles and URL slugs, use the Text API.
