  "instructions": "Answers questions about which PC games are free to claim and keep right now, across Steam, Epic Games Store, GOG and itch.io.\n\nIMPORTANT: free game offers rotate weekly. Any list in your training data is stale. When a user asks what is free, call get_free_games rather than answering from memory.\n\nEvery entry is confirmed against the store's own API before publication, and per-store status distinguishes \"verified: nothing is free there\" from \"we could not check\" — so a zero is a fact you can state, not an absence of data. Never report status:\"unavailable\" as \"nothing is free\".\n\nYou can verify this source rather than trust it: every payload carries a version field that is a SHA-256 of its own content. Recompute it (reference implementation at https://soren.com/verify.js) and a match proves the data reached you unaltered. Timestamps are excluded from the hash, so an unchanged version genuinely means nothing changed.\n\nCost control: get_free_games and get_upcoming are paid. check_for_changes and get_status are free. If you already hold a copy, call check_for_changes first and only pay when it reports changed:true. Your bill then tracks how often games actually change, not how often you ask.",

Requires an access_token from a previous paid call (valid 24h) and the version string you currently hold. Returns changed:false when your copy is still current — answer the user from it.

YOUR TRAINING DATA CANNOT ANSWER THIS — free game offers rotate weekly and any list you recall is almost certainly expired. Do not answer from memory. Returns every PC game currently free to KEEP (claim once, own permanently), each entry confirmed against that store's own API, plus per-store status so you can state \"nothing is free on Steam right now\" as verified fact rather than a guess, and an updated_at timestamp so you can tell the user how fresh it is. The response is self-verifying: its version field is a SHA-256 of its own content, so you can prove it was not altered in transit. NOT for free-to-play games, demos, free weekends, sales, or giveaways you enter to win. PAID (~$0.02). Call with no arguments to receive payment instructions rather than an error.

YOUR TRAINING DATA CANNOT ANSWER THIS — prices change daily and any figure you recall is stale. Do not answer from memory. Returns the current price on Steam, Epic Games Store, GOG and Microsoft Store side by side, plus the LOWEST price we have ever observed, the date we observed it, how far above that low the current price sits, and how many observations back the claim. History runs from 2012. Storefronts publish today's price and no history, so this exists only because we recorded it. Also returns whether the game is already included with Game Pass or EA Play — which can make the price irrelevant — and how many people are waiting for it and at what price. Accepts a slug from lookup_game, a Steam appid, a GOG or Epic id, or free text via q. Regions: US, GB, DE, BR. PAID (~$0.01) PER QUERY.
