Available deployment channels
The Napster Companion API lets you deploy the same agent across multiple channels. The agent maintains the same identity, knowledge, and behavior regardless of how users connect.
Video — Web SDK (WebRTC)
Real-time 2D avatars with synchronized lip-sync and natural expressions. Embed directly in any web page using the JavaScript Web SDK. Three avatar view modes: Round (face-focused), Rectangle (full body with background), and Silhouette (full body, background removed).
Audio — WebSocket
Voice-only agents for lightweight, audio-first experiences. Uses a persistent WebSocket connection for real-time audio streaming from any environment — browser, mobile, or server.
Telephony — VoIP / SIP
Connect agents to phone lines to handle inbound calls. VoIP and SIP support is currently in progress and coming soon.
Tip: Average response latency is approximately 300ms across all channels. The platform supports around 30 languages.
