Get price/discount, review % (positive), hardware compatibility, popular user tags and release date for a LIST of games by appid in ONE keyless call. The efficient way to price-, rating-, tag- and compat-check a wishlist or library without a request per game. For a bigger batch (up to 500 appids) when you only need price, use get_prices instead. An unknown/invalid appid comes back as its own row marked available:false (never dropped from the list), same as get_prices. Each item carries four compatibility fields, each verified/playable/unsupported/unknown: steam_deck (Steam Deck), steam_os (SteamOS in general), steam_machine (the Steam Machine console specifically), and steam_frame (Steam Frame VR headset); a `vr_support` flag (none/supported/required — distinct from steam_frame, which is a Steam Frame HARDWARE compat rating, not whether the game itself has a VR mode); a `tags` list (top user tags like 'Roguelike', 'Souls-like', most-relevant first); a clickable `store_url` to the game's Steam page; and, when on sale, `discount_end` (ISO UTC time the discount expires — for 'how long is this deal valid'). To find NEW games by filter (discount, rating, tags, compat) instead of pricing a list you already have, use discover_games instead. Get appids from search_games / get_wishlist / get_owned_games.
