ProtonDB Steam Deck & Linux Compatibility API

healthy 4,385 Subscribers

Live Linux and Steam Deck compatibility plus popularity for Steam games, from the public ProtonDB and Steam feeds — no key, nothing stored. The "can I play it on Linux / Steam Deck, and is anyone playing it" view of a game: the crowd-sourced ProtonDB compatibility tier together with the live concurrent-player count, distinct from the other game and platform APIs in the catalogue. The game endpoint returns a full picture for a title — its Steam name, genres and release date, the ProtonDB compatibility tier (platinum, gold, silver, bronze or borked) with the community confidence, score and report count, the trending and best-reported tiers, and the live player count. The search endpoint resolves a game name to its Steam app id and other matches, so you can find the id to query. The players endpoint returns just the live concurrent-player count for a game. Build Steam Deck compatibility checkers, Linux gaming dashboards, "is it playable" widgets and game-popularity trackers on top of real ProtonDB and Steam data. Look up a game by Steam app id (appid=1245620) or by name (name=elden ring); ProtonDB tiers run from platinum (flawless) down to borked, and player counts are live.

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.

Book Reader Stats API

Live reader-community stats for books from Open Library (the Internet Archive's open book catalog) — no key, nothing stored. This is the reading-community view of a book: how readers rate it and how many want to read, are reading or have already read it, distinct from the plain book-catalog and reading-trends APIs in the catalogue — this is the community-engagement layer, not the bibliographic record. The book endpoint returns a title's reader stats: the average rating, the full 1-5 star distribution, and the reading-log counts (want-to-read, currently-reading, already-read), with its authors, first-published year and subjects. The search endpoint searches books and returns each match with its rating and want-to-read count, so you can find a work and its Open Library id. The author endpoint returns an author's profile — work count, top work and dates. Build reading dashboards, book-recommendation widgets, "most wanted" charts and community-sentiment tools on top of real Open Library data. Look up a book by its Open Library work id (work=OL27448W) or by title (title=the hobbit); reading-log counts come from the community's bookshelves.

MyAnimeList Community Stats API

Live anime community stats from MyAnimeList, the world's largest anime and manga community, via the public Jikan feed — no key, nothing stored. The MAL community view: a title's MAL score, member counts, ranking and the full engagement breakdown of how the community is watching it, distinct from the other anime platforms in the catalogue — MyAnimeList has its own score, its own millions-strong community and its own rankings. The anime endpoint returns a title snapshot: the MAL score, how many users scored it, its rank and popularity rank, total members, favourites, airing status, episode count and year. The stats endpoint returns the community engagement breakdown — how many users are watching, completed, on-hold, dropped or plan-to-watch — plus the full 1–10 score distribution with vote counts and percentages, and computed completion and drop rates. The top endpoint returns the top-ranked anime, by score or filtered by airing, upcoming, popularity or favourites. The season endpoint returns the anime airing this season ranked by member count. Build anime trackers, recommendation widgets, seasonal-airing dashboards and community-sentiment tools on top of real MyAnimeList data. Look up a title by its MAL id (try id=52991, Frieren).

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.
