# ProtonDB Steam Deck & Linux Compatibility API
> 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.
