WebAPI

The Steam Web API is documented at http://steamcommunity.com/dev and http://developer.valvesoftware.com/wiki/Steam_Web_API.

This page documents the web API calls that allow you to retrieve information from the item system in Team Fortress 2.

Each example URL requires a valid API Key to replace "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" to function. You can get your own API Key here.
