The Steam Inventory API lets you retrieve live CS2 inventory data directly from Steam. You can fetch your own inventory using your linked Steam account, or look up any player’s public inventory by their Steam64 ID or vanity URL. Inventory data is fetched live on every request and is never stored by CS2Cap.

​
GET /inventory/steam

Returns the authenticated user’s live CS2 inventory from Steam. A linked Steam account is required — connect yours in your account settings before calling this endpoint. Auth: Bearer token + linked Steam account · Rate limit: Standard per-tier RPM
