TF2 Price, Market & Inventory API
Build TF2 item catalogues, marketplace price comparisons and backpack tools through three documented APIs.

Use Steam App ID 440 with the three core Team Fortress 2 API products. Each product has a distinct data purpose and links to its dedicated page.

TF2 Price, Market and Inventory API examples
Use the same game parameter mapped to Steam App ID 440 across the Items and Inventory endpoints. Add a market filter when you only need selected third-party prices.

Three TF2 APIs for items, prices and inventories
Team Fortress 2 uses Steam App ID 440. The TF2 Price API returns supported item data and current prices, the TF2 Market API exposes supported third-party prices, and the TF2 Inventory API retrieves public backpack data.
Use these endpoints for a TF2 item catalogue, price tracker, marketplace comparison or inventory checker. Responses are normalized where supported, while coverage and freshness remain explicit for each data source.
