SteamSpy Game Analytics API
Steam game ownership and player analytics as an API, powered by SteamSpy — clean JSON, no key. Look up any Steam game by app id for its estimated owners, current concurrent players, average and median playtime (all-time and last two weeks), price and discount, positive/negative review counts and review score, developer, publisher, genre, languages and top community tags. Pull the top-100 lists — games by current players, by all-time playtime and by estimated owners — and list the top games in any genre or with any tag. Live market data straight from SteamSpy. Distinct from the Steam store: this is the ownership and engagement layer — ideal for game-market research, indie-dev competitor analysis, trend dashboards and charts. 6 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.
