Three s&box APIs for items, prices and inventories
s&box uses Steam App ID 590830. The s&box Price API returns supported item data and current prices, the s&box Market API exposes supported third-party prices, and the s&box Inventory API retrieves public inventories.
Use these endpoints for a s&box item catalogue, price tracker, marketplace comparison or inventory checker. Responses are normalized where supported, while coverage and freshness remain explicit for each data source.
