Developer platform

Build interactions that answer in real time.

Bring speech, character video, live sessions, and agents into one product experience. Sunesis gives your team a consistent set of APIs, streaming patterns, and workspace controls from the first prototype through production.

Built to stay connected

Less integration drift. More room to ship.

One development model

Keep the same project credentials, usage controls, webhook conventions, and SDK patterns as your product grows.

Streaming where it matters

Build responsive interactions around streamed audio, live turn events, and incremental state updates.

Controls for the team

Organize keys and workspace access without making every product surface feel like a separate system.

Ready for the handoff

Move from an experiment to a production workflow with clear integration paths and implementation guidance.

Deployment choices

A practical path from launch to scale.

Hosted API

The fastest route from a working prototype to a product your team can keep refining. Start with the endpoints you need and expand the experience over time.

  • REST and WebSocket patterns
  • Voice, characters, live sessions, and agents
  • Shared project controls and usage views
  • Docs and SDK guidance for your team

Custom delivery

For teams with specific deployment, security, or operational requirements, Sunesis can help shape an integration and support model around the product you are building.

  • Solution design for your application
  • Deployment and access planning
  • Product and workflow guidance
  • A direct path to the right team
Talk to sales
Ready for the next stage

Build the product, not four separate integrations.

Workspace-aware access

Keep the controls, ownership, and environments your team needs in the same place as daily development.

SDKs and direct APIs

Use the approach that suits your stack: typed SDKs, REST endpoints, or a WebSocket connection for live sessions.

A path for complex delivery

When the product grows beyond a standard integration, the platform and team can grow with it.
