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.

AtCoder Rating & Contest API — oanor API marketplace

AtCoder Rating & Contest API

Live competitive-programming rating data from AtCoder, the largest Japanese competitive-programming platform, over its public rating-history feed — no key, nothing stored. This is the contest-rating social view for a coder: their AtCoder rating, colour tier, contest record and performance over time, distinct from the other competitive-programming and developer platforms in the catalogue — AtCoder runs its own AGC/ABC contests, its own rating system and its own community. The user endpoint returns a profile snapshot: current rating, peak rating, the AtCoder colour tier (gray, brown, green, cyan, blue, yellow, orange, red), the number of rated contests, the best placing, the best performance and the latest contest. The history endpoint returns the full per-contest rating timeline — each contest with its date, old and new rating, the rating delta, placing, performance and whether it counted as rated. The stats endpoint aggregates a coder's record: rated versus unrated contests, average and best performance, contest wins, podium finishes, the rating range and per-year activity. Build coder leaderboards, rating cards, contest-tracking bots and recruiting signals on top of real AtCoder data. Lookup is by handle; the legendary handle "tourist" is always available.

 LeetCode API — oanor API marketplace

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).

 OpenProcessing Creative Coding API — oanor API marketplace

OpenProcessing Creative Coding API

Live creator and sketch data from OpenProcessing, the community for Processing and p5.js creative-coding sketches, served from its public API. The user endpoint returns a creator's profile — username, name, bio, location, website, join date and total sketch count. The sketches endpoint lists a creator's published sketches with title, license, engine mode and dates. The sketch endpoint returns a single sketch's detail — title, description, tags, license, libraries used, the fork parent it was remixed from, and the author. The social endpoint returns a creator's followers or the accounts they follow. This is a creative-coding community stats API — creator profiles, sketch catalogues and the follow graph — distinct from the code-hosting, package-registry and other social-platform APIs in the catalogue. A user is a numeric OpenProcessing userID and a sketch is a numeric visualID, both visible in OpenProcessing URLs. Live, no key on the upstream, nothing stored.

 Modrinth Minecraft Mods API — oanor API marketplace

Modrinth Minecraft Mods API

Live mod-platform stats from Modrinth, the open Minecraft content platform — no key, nothing stored. The adoption-and-community view of the Minecraft modding ecosystem: how much each mod, modpack, shader or resource pack is downloaded and followed, and which projects are most popular, distinct from the other developer-ecosystem and gaming APIs in the catalogue. The project endpoint returns a single project in full — total downloads, followers, type, categories, supported game versions and loaders, client/server sides and license. The search endpoint searches projects, filterable by type (mod, modpack, shader, resource pack, data pack) and sortable by downloads or follows, each with its download and follower count. The versions endpoint returns a project's recent releases with per-version downloads, supported game versions and loaders. Build mod dashboards, popularity trackers, "is this mod maintained" widgets and modpack browsers on top of real Modrinth data. Look up a project by its slug (sodium, iris, fabric-api); downloads are the headline popularity metric.
