Meet the Napster API
The foundational layer powering multimodal coworkers across every surface your customer touches. Create an Omniagent — an AI agent with a persistent identity, voice, and visual appearance that carries its knowledge, memory, and actions across website, apps, phone, and beyond. One API, one agent, every channel.
Add an AI agent that operates your website.
Not just a chat bubble — visitors ask in their own words, and the agent searches, navigates, fills, and books through your site's real functions, while the page updates in front of them.
Stage 1: Agentify the website
To agentify a website, install Edge MCP and expose the operations and live state you choose from your own code. One prompt in your AI coding tool does the integration.
Edge MCPStage 2: Add the AI agent
Next, add the agent with the Web SDK. It discovers your tools automatically, so it operates the site while it talks to the visitor.
Web SDK
Or build it yourself
Follow the path. Each step links to the in-depth resource you need.
Get an API key
Sign up at napster.com/developer — new accounts start with $6 of free credits, roughly 100 minutes of conversation. Prefer billing through your Azure subscription? Create a resource in the Azure Portal instead. Either way, you then generate an API key from the dashboard — see Authentication for details on how to authenticate API calls.
Build
Pick a companion, add knowledge and tools, configure voice and settings — then create your Omniagent.
Deploy
Choose a channel — WebRTC, WebSocket, VoIP, or SIP — and go live. Same agent, every surface.
Monitor
Track sessions, review transcripts, and refine your agent over time.
Explore by topic
Identity
Define your agent's role, persona, voice, and visual appearance. Consistent across every session and channel.
Knowledge
Give your agent domain expertise with files, FAQs, and structured data.
Memory
Your agent remembers who it's talking to — across sessions and channels.
Actions
Connect your agent to real systems through tools and functions.
WebRTC
Browser-based voice and video via the Web SDK.
WebSockets
Audio-only streaming for apps and custom integrations.
VoIP
Put your agent on any phone number in minutes. No trunk credentials — just a webhook URL you register with Twilio.
SIP
Answer phone calls with your own SIP trunk. Human handoff, custom routing, and enterprise telephony integration.
