What can you build with Steam Web API?
Steam Web API is a Media API. Developers commonly use media APIs for:
- storing and delivering images, video, and audio
- building digital asset management and media libraries
- transcoding and optimising media for the web
- adding video streaming and playback to your app
- automating content tagging and metadata extraction
API Key authentication. You'll receive a key after signing up. Send it with every request — in a header or query parameter. Keep it out of client-side code and never commit it to version control. Steam Web API is free to use up to a usage limit, making it a low-risk choice to experiment with.
