About Steam

This GitHub wiki documents an unofficial, community-compiled reference for internal Steam Web API endpoints not part of Steam's official public API. It lists undocumented HTTP GET routes covering areas such as the Steam store (app details, packages, search, discounts), the Steam Community (comments on profiles, clans, forum topics, recommendations), broadcasts, the marketplace (listings, price history, order activity), inventories, friends data, mobile confirmations, and user profile/notification data. Many listed endpoints require an authenticated Steam session to access.

The resource is aimed at developers building tools or integrations that interact with Steam beyond what Valve's official Web API exposes, such as third-party market, inventory, or community-data applications. It is maintained as a wiki with community edits, reflecting ongoing discovery and documentation of these internal endpoints rather than an official specification from Valve.
