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.

Codewars API — oanor API marketplace

Codewars API

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.

Habr Tech Community API — oanor API marketplace

Habr Tech Community API

Articles, ratings and topic hubs from Habr (habr.com), the largest Russian-speaking technology community, read keyless from its public web API. Habr is where Russian-speaking engineers, scientists and companies publish deep technical articles, and where the community judges them with a signed rating (up-votes minus down-votes) — a score that can go negative, quite unlike a likes-only model. Alongside the rating, every article carries its read count, bookmarks (saves) and comments, and lives in one or more "hubs" (topic communities). The articles endpoint lists the top articles, ranked either by rating over a period (day/week/month/year/all-time) or by date, each with its signed score, vote count, reads, bookmarks, comments, author, hubs and reading time. The article endpoint returns one article in full by its numeric id. The hubs endpoint lists Habr's topic hubs with their subscriber counts and hub rating — the map of Russian tech's interests (AI, information security, programming and the rest). This is the Habr platform cut — a distinct social and developer platform, separate from the Western (dev.to) and Japanese (Qiita) developer communities in the catalogue, with its own signed-rating model and Russian-language community. Scores, reads and subscriber counts are the real, live numbers; a negative score is real, not an error. Titles and hubs are in Russian as Habr publishes them. A short cache fronts the upstream. Keyless.

Qiita Developer Community API — oanor API marketplace

Qiita Developer Community API

Articles, engagement and trending tech tags from Qiita (qiita.com), Japan's largest developer knowledge-sharing community, read keyless from its public v2 API. Qiita is where Japanese engineers post how-tos, deep-dives and notes, and where the community signals quality with LGTM ("looks good to me") likes and "stocks" (saves) — the Japanese counterpart to dev.to or Medium's engineering side, with its own metrics and its own tech-topic rankings. The articles endpoint searches and lists articles, each with its title, LGTM likes, stocks (saves), comment count, tags and author — filterable by keyword, tag and a minimum-stocks threshold so you can surface the popular pieces. The article endpoint returns one article in full by its id. The tags endpoint ranks Qiita's tech tags by how many articles and followers they have — the live map of what Japanese engineers care about (Python, AWS, React and the rest). This is the Qiita platform cut — a distinct social and developer platform, separate from dev.to, Medium and the other blogging and social feeds in the catalogue, with its own LGTM/stock engagement model. Likes are LGTM up-votes and stocks are saves/bookmarks — two distinct Qiita signals; follower and article counts are the real, live community numbers. Titles and tags are in Japanese (and English) as Qiita publishes them. Qiita rate-limits unauthenticated callers, so a longer protective cache fronts the upstream and stale data is served if the limit is hit. Keyless.
