Every endpoint on this page requires either a Clerk-issued JWT (Authorization: Bearer <token>) or an organization API key (x-api-key: pk_…). Anonymous calls return 401 Unauthorized. See Authentication for the full setup.
The agent must have voiceEnabled: true and a voicePipelineMode set. See Create Agent for voice configuration details.

Connecting via LiveKit

Use the token and serverUrl from the response to connect with the LiveKit client SDK:
Node.js
import { Room, RoomEvent, Track } from 'livekit-client';

const room = new Room({
  adaptiveStream: true,
  dynacast: true,
});

room.on(RoomEvent.TrackSubscribed, (track) => {
  if (track.kind === Track.Kind.Audio) {
    track.attach(); // plays agent audio in the browser
  }
});

await room.connect(serverUrl, token);
await room.localParticipant.setMicrophoneEnabled(true);
