Omniagent API is live, and Napster is celebrating with a global hackathon that runs alongside Microsoft Build June 2-3 in San Francisco.

The company’s newly-launched developer tool gives any team a way to instantly transform an existing AI agent into a fully multimodal, interactive video agent through a simple proxy API. Launching exclusively with Microsoft, Omniagent is available now as an Azure Native Solution.

A year ago, companies were asking how to get their teams to use a general-purpose LLM. Today, they're asking how to get an agent to show up the way their people do: across channels, in context, with a face, and on their terms. Omniagent API is built for that shift, and Build will be the first public showcase of its capabilities, including virtual and in-person demos, tech walkthroughs at Napster’s booth, and a hackathon to let developers discover the most creative and ambitious ways to leverage this tool.

What is Omniagent API?

Omniagent API sits on top of existing real-time infrastructure as a lightweight proxy, so developers can add a video layer to agents they've already built without rewriting the underlying code or taking a hit on latency. At $0.01 per minute, it makes embodied agents viable for high-volume deployments in customer service, in-store assistance, financial services, and mobility that have been priced out of the conversation until now.

Agents can appear as generated or customized avatars based on a single image, or as digital twins of an actual person. They're model-agnostic by design, so enterprises can build on their own proprietary systems or whatever frontier model fits the job.

The launch deepens Napster’s partnership with Microsoft and gives Azure customers a way to deploy embodied agents inside the security and governance perimeter they already trust. As enterprises move from experimentation to production, the question of who owns the data and the customer relationship becomes the difference between a one-off pilot and a long-term platform decision. Omniagent API is built so the answer stays with the company deploying it. Your prompts, your conversations, your persona, and the data and insight that compounds across every customer interaction belong to your business.

What Napster’s doing at Build

Build is one of the most important moments of the year for the developer ecosystem, and Napster is showing up in a few ways.

A global hackathon. Starting May 18, developers can register, get a scoped API key, and build with Omniagent API, with top entrants winning hardware, merch, and amplification of their creations across Napster’s channels. 

Categories include: 

• Best multi-surface integration
• Best creative use case
• Best production-ready build
• Best use of memory continuity

Registration is open now on the hackathon landing page, along with competition rules and access to an active community channel where Napster engineers will be available throughout the build window.

Lightning Talk and tech demos. Napster Chief Technology and Product Officer Edo Segal will host a Lightning Talk at Build focused on creating multimodal agents that act as coworkers and collaborators, as well as a live demo of Omniagent API in action. A virtual tech demo hosted by Edo and Chief Product Officer Ziv Navoth will run alongside the talks and give attendees worldwide a look at what the API can do.

Booth G-224 at Fort Mason. Throughout the event, Napster will be showing off Omniagent API use cases at its booth, meeting with fellow developers and engineers, and talking about the massive leap in capability AI has displayed since the start of the year. Come by for a chat, tell us what you're working on, and learn how we can help.

The bigger picture

The work of 2026 will be the shift from AI chats to conversations, from one surface to many, from generic LLM access to agents that understand a specific business and the people inside it. Omniagent API is one driver of that shift, and Build is where many of the developers who will build the rest of it gather.

If you're working on something that an embodied agent could change, Napster wants to help. Register for the hackathon, set up a meeting at Build, find us at Booth G-224, or email partners@napster.com.

We'll see you in San Francisco.
