What is Napster Companion API?
Napster Companion API is Napster’s platform for building Omniagents: persistent, multi-channel AI agents with one identity, one memory, and one set of tools that show up across every channel an end user touches.
The same Omniagent meets the customer on the website, in the mobile app, on video, and on the phone line with the same face, the same voice, and the same memory of the last conversation.
The Omniagent as a digital worker
The clearest way to think about an Omniagent is as a digital worker:
- It has a role (customer support specialist, sales advisor, internal IT assistant).
- It carries the memory of past shifts and prior conversations.
- It has the tools it needs to do the job which include APIs, knowledge bases, ticketing systems, CRMs.
- It shows up across every surface the end user touches, like a human worker who answers the door, the phone, and the inbox.
- When something is outside its scope, it hands off to a human colleague with the context already attached and picks the thread back up when the human is done.
Use cases for the Companion API
Teams are already exploring the Companion API across a wide range of scenarios:
- Agentic commerce. Agents that guide end users through discovery, recommendations, purchase, and post-sales support all in one continuous conversation across channels.
- Customer service. Agents that resolve issues end to end, escalate to humans with full context attached, and pick the thread back up across sessions.
- Internal operations and digital coworkers. Agents that orchestrate workflows, retrieve knowledge, and automate repetitive tasks for the workforce.
Capabilities introduced by Napster Companion API
The Companion API public preview brings the following capabilities to Azure customers:
- Persistent multi-channel agents that maintain identity, memory, and context across web, mobile, voice, video, and telephony.
- Real-time multimodal interactions across voice, video, and text for natural back-and-forth conversation.
- Tool and API orchestration that lets agents take real actions like opening tickets, updating records, retrieving documents, and triggering workflows.
- Persona-driven agents with configurable behavior, conversational style, and avatar-based interaction.
- Knowledge bases and deterministic question-and-answer pairs for grounded, accurate responses on topics where exactness matters.
- Developer SDKs and a no-code Dashboard for building, testing, deploying, and iterating on agents.
Better together: Napster and Microsoft
This integration is the result of a long-term Azure-native partnership between Napster and Microsoft. It is not an external service layered onto Azure infrastructure but it is a co-engineered offering designed to help enterprises operationalize persistent AI agents at scale.
In practice, the Azure Native integration delivers:
|
Benefit |
What it means for you |
|
Seamless development experience |
Provision and manage Companion API resources directly from the Azure portal, alongside your other Azure services. Build and operate Omniagents in the Napster Dashboard, reached through single sign-on. |
|
Bring your own model or use Napster Hosted |
Connect your Azure OpenAI realtime deployment on Microsoft Foundry so inference runs in your tenant. Or use the Napster Hosted tier where Napster manages the model for you. |
|
Simplified billing |
Manage Companion API spend through Azure Marketplace, on the same invoice as the rest of your Azure consumption which means no separate procurement, no separate billing relationship. |
|
Single sign-on with Microsoft Entra |
Switch between Azure resources and the Companion API Dashboard without re-entering credentials. |
|
Enterprise-ready foundation |
Built on Azure’s compliance, security, and global infrastructure footprint. |
