  title: AssemblyAI Voice Agents API
  description: >
    REST API for creating and managing reusable voice agents. An agent stores
    its

    system prompt, greeting, voice, and tools server-side, so you can deploy the
    same

    agent across the WebSocket API, a browser, or Twilio by referencing its
    `id`. See

    [Create an agent](/voice-agents/voice-agent-api/create-agent)

    for a guided walkthrough.
