TF2 (Team Fortress 2) is an online, team-based, multiplayer first-person shooter game developed by Valve. In TF2, the backpack is a player's personal inventory which stores all in-game items. Items are kept in individual slots and can be viewed, moved, or deleted. The TF2 Backpack Explorer API is a service that shows item pricing data as well as the contents of a given player's backpack.
