title: "TypeScript SDK"
description: "Generated types and a thin fetch-based client."
---

The TypeScript SDK is generated from the OpenAPI spec produced by the Rust server.

## Generate types

```bash
pnpm --filter sandbox-agent generate
```

This runs:

- `cargo run -p sandbox-agent-openapi-gen -- --out docs/openapi.json` to emit OpenAPI JSON
- `openapi-typescript` to generate types

## Usage

```ts
import { SandboxDaemonClient } from "sandbox-agent";

const client = new SandboxDaemonClient({
  baseUrl: "http://127.0.0.1:2468",
  token: process.env.SANDBOX_TOKEN,
});

await client.createSession("my-session", { agent: "claude" });
await client.postMessage("my-session", { message: "Hello" });
const events = await client.getEvents("my-session", { offset: 0, limit: 50 });
```

## Autospawn (Node only)

```ts
import { connectSandboxDaemonClient } from "sandbox-agent";

const client = await connectSandboxDaemonClient({
  spawn: { enabled: true },
});

await client.createSession("my-session", { agent: "claude" });
await client.postMessage("my-session", { message: "Hello" });

await client.dispose();
```

Autospawn uses the local `sandbox-agent` binary. Install `@sandbox-agent/cli` (recommended), or
set `SANDBOX_AGENT_BIN` to the binary path.
