Vocode is an open-source Python library (vocode-core, MIT licensed) for building real-time, streaming voice AI agents that run over phone calls, plus a hosted REST API at https://api.vocode.dev/v1 (Bearer API key) for placing and managing outbound and inbound phone calls, configuring agents, voices, prompts, actions, phone numbers, and webhooks without operating the streaming infrastructure yourself.

Real-time, bidirectional streaming conversation pipeline (StreamingConversation) in the open-source library that wires transcription, agent response, and synthesis together; the hosted platform consumes telephony media-stream WebSockets, but no public client-facing wss conversation endpoint is documented in the hosted REST API.
