🟢get_cheapest_way_to_play(game_id, region, currency, include_marketplaces)
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(game_id, region, currency, include_marketplaces)
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(game_id, region)
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.

}🟢search_games(query)
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).

}🟢list_deals(kind, region, currency, limit)
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.
