Quickstart

Import the Stream class and pass in a handler. The Stream has three main methods:

• .ui.launch(): Launch a built-in UI for easily testing and sharing your stream. Built with Gradio.
• .fastphone(): Get a free temporary phone number to call into your stream. Hugging Face token required.
• .mount(app): Mount the stream on a FastAPI app. Perfect for integrating with your already existing production system.
