CS2 Price, Market & Inventory API
Build CS2 skin catalogues, price comparisons and inventory tools with three purpose-built APIs and one Steamwebapi key.

Use Steam App ID 730 with the three core Counter-Strike 2 API products. Each product has a distinct data purpose and links to its dedicated page.

CS2 Price, Market and Inventory API examples
Use the same game parameter mapped to Steam App ID 730 across the Items and Inventory endpoints. Add a market filter when you only need selected third-party prices.

Three CS2 APIs for skins, prices and inventories
Counter-Strike 2 uses Steam App ID 730. The CS2 Price API returns the supported skin catalogue and current prices, the CS2 Market API compares third-party marketplaces, and the CS2 Inventory API retrieves public player inventories.
Use these endpoints for a CS2 item catalogue, price tracker, marketplace comparison or inventory checker. Responses are normalized where supported, while coverage and freshness remain explicit for each data source.
