Managed agents · for developers

Embed dedicated agents, via API.

Create an agent with a persona and tool allowlist, open sessions from your backend, stream replies over SSE - with optional sandbox jobs that build deliverables headless.

Architecture

Four hops from your backend to a running agent.

Your backend calls with a scoped key; the API isolates the session per app, loads the persona and allowlist, and streams. The same harness that runs the workspace runs your agent.

Your backendYour stack

One call per session - no SDK lock-in

API keyScoped

Auth + metering, isolated per app

What each agent carries

Persona & allowlist

Voice, instructions, and exactly the tools this agent may call - nothing more.

Assist mode (SSE)

Replies stream token by token into your UI - the same loop your users see in chat.

Sandbox deliverables

Optional headless jobs build documents and reports, filed back to storage.

Session isolation

Every session scoped to one app. No context crosses between your apps or tenants.

API reference

Routes and examples live in the docs.

Create agents, open sessions, stream replies, and run headless jobs. The full contract is on the docs site - not duplicated on this page.
