A community-maintained wiki documenting unofficial and internal Steam Web API endpoints.
UnofficialSteamWebAPI is a community-maintained wiki that documents the unofficial and internal web APIs used by the Steam platform. It provides developers with insights into endpoints that are not part of the official Steam Web API, enabling deeper integration and automation with Steam services. The project addresses the lack of official documentation for these internal endpoints, which are often discovered through reverse engineering.
Developers and researchers working with the Steam platform who need to access undocumented features, automate interactions, or build tools that rely on Steam's backend services beyond the official API limits.
It offers a centralized, collaborative resource for undocumented Steam APIs, saving developers time from reverse-engineering endpoints themselves and fostering a community-driven approach to keeping the documentation current and comprehensive.
Documenting the unofficial and internal Steam Web API
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides detailed descriptions of internal Steam API endpoints with parameters and example responses, filling gaps left by the official API.
Uses a wiki format that encourages updates and contributions, keeping the documentation dynamic and collectively maintained.
Includes guidance and a JavaScript script for generating documentation from network traffic, aiding in endpoint discovery as highlighted in the README.
Demystifies Steam's internal APIs through collective sharing, making them accessible without proprietary barriers.
The documentation generation script cannot detect variables like appids, requiring manual correction, as admitted in the README.
The wiki's accuracy depends on ongoing contributions, which may not keep pace with API changes, leading to incomplete or outdated information.
Unofficial APIs are internal and can be altered or removed by Valve without notice, causing applications to break unexpectedly.
