Items

App Price List

Get a full price list for all market items of a given Steam app, redirecting to a pre-generated file whose contents depend on your history plan.

Endpoint

This endpoint returns a comprehensive pre-generated price list for every market item tracked for a given Steam app — including current price summaries, volume, order book depth, signals, and flags. It's intended for bulk consumers (e.g. syncing a local price cache for an entire app's market).

The endpoint redirects (HTTP 302) to a pre-generated JSON file hosted on SteamApis' CDN. The exact contents of that file depend on your active history plan — plans with more history expose deeper prices windows (for example, 180d and all). Your HTTP client should follow redirects automatically.

Because the payload is pre-generated and returned as a plain file, the response is not wrapped in the usual { "success": true, "result": {...} } envelope. The redirected file's top level is directly { metadata, items }.

GET /v2/steam/items/{appid}/list

Required parameters

appid

number

The Steam application ID whose item price list you want to fetch.

Authentication

Include your API key as the x-api-key request header.
