  title: Pipecat Cloud Agents Sessions API
  description: REST control API for Pipecat Cloud, the hosted platform for deploying and operating agents built with the open-source Pipecat Python framework. The Pipecat framework itself is an SDK (the pipecat-ai Python library) and does not expose a REST API; its interface is Python Pipelines, Frames, FrameProcessors, Services, and Transports (Daily WebRTC, SmallWebRTC, LiveKit, FastAPI WebSocket, and telephony serializers). This document models only the documented Pipecat Cloud REST control plane - managing agents, starting and stopping sessions, builds, secrets, organization properties, and regions. Realtime media (audio/video) flows over WebRTC/WebSocket transports negotiated out of band and is not modeled as REST here.
