## Tools (4)

- `browse_platform`: One platform's games with their prices, most popular first or by price: the most valuable games on a console, the cheapest, A to Z. Optionally only PAL, NTSC or Japanese releases.
- `get_game_prices`: What one game sells for, from completed sales: the range and typical price of loose, incomplete, complete, sealed and graded copies, each region's and each edition's price, how fast it sells and its newest sales. Name the game by its page URL from search_games, optionally a region and an edition.
- `list_platforms`: Every platform the price guide covers, with its slug (for the other tools), its number of games and its page URL.
- `search_games`: Find video games by name, on every platform or one. Each match comes with its platform, its page URL and what loose, complete and sealed copies typically sell for.
