[Stream](https://getstream.io/) maintains **[Vision Agents](https://visionagents.ai)**—an open-source Python framework for voice- and vision-driven agents with realtime media over **Stream**’s WebRTC edge. Cartesia is supported as the **TTS** provider; install steps, environment variables, and parameters are in Stream’s **[Cartesia integration](https://visionagents.ai/integrations/cartesia)**.

You need a **Stream** developer account for realtime transport and a **Cartesia API key** for speech.

The ["Simple Agent"](https://github.com/GetStream/Vision-Agents/tree/main/examples/01_simple_agent_example) example in GitHub and the [voice](https://visionagents.ai/introduction/voice-agents) / [video](https://visionagents.ai/introduction/video-agents) intros are good starting points.
