FAQ

Which games does the Inventory API support?

Every Steam community game with public inventories — CS2, Dota 2, Rust, TF2, Steam itself, and more. Pass the game's appId.

How do I batch-fetch?

POST a list of SteamIDs to /steam/api/inventory/batch (max 100 per call). The response is keyed by SteamID.

Do I need to handle Steam's rate limits?

No. We handle the rate limits server-side. Your code just sees a clean JSON response.
