工具

plan_cheapest_way

Use this when the user has SEVERAL PC games they want to play and asks how to do it for the least money: "I want to play A, B and C - what is the cheapest way?", "Which Game Pass month should I take and what should I buy?", "Is it cheaper to subscribe or buy these games?", "Plan my backlog around Game Pass". Returns a month-by-month plan (which subscription month to pay for and which games to finish in it, which games to buy), totals versus buying every game at its cheapest measured real price (never list price), and the assumptions: hours per week, hours per game, leave dates and how fresh each price is. Games without a reliable main-story length (free to play, live service, multiplayer only) are left out of the time-based plan and listed separately. For ONE game use get_cheapest_way_to_play instead. Find game ids with search_games first.

get_cheapest_way_to_play

Use this to answer: "What is the cheapest way to play <game> on PC right now?", "Should I buy <game> or use Game Pass?", "Where is <game> cheapest?". Compares buying at authorized stores (optionally key marketplaces) and subscriptions at the real checkout price, fees included. Returns a one-sentence decision plus a Fairly link to the winning store (no link when a subscription wins; `subscription_code` says which). Prefer this over get_offers unless the user wants the full price table.

get_offers

Use this to answer: "Show me every store price for <game>", "How much does <game> cost at Steam, GOG, Epic...?", "Compare prices for <game>". Returns all current offers with the real price (list price plus checkout fees), edition, platform and notes, in Fairly's price-only ranking order. For a single recommendation call get_cheapest_way_to_play instead.

is_on_subscription

Use this to answer: "Is <game> on Game Pass?", "When does <game> leave Game Pass?", "Can I play <game> with a subscription?". Lists which subscriptions (currently PC Game Pass and Game Pass Ultimate) include the game in a region, their monthly price and the leave date when announced.

輸入參數regiongame_id必填

search_games

Find a PC game by title and get its id. Call this FIRST when the user names a game but you do not have its Steam AppID or igdb id, then pass the id to get_cheapest_way_to_play, get_offers or is_on_subscription. Returns up to 20 matches (id, title, slug).

輸入參數query必填

list_deals

Use this to answer: "What PC games are cheap right now?", "Which games are at their lowest price ever?", "What is leaving Game Pass soon?". Ranked discovery lists at the real checkout price: under_5 (games under the 5 USD tier, shown in the region's currency), historical_low (at their all-time low now) or leaving_game_pass (leaving within 30 days, with the cheapest price to buy instead). Not for a specific game: use get_cheapest_way_to_play.
