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/typescript-sdk generate
```

This runs:

- `cargo run -p sandbox-agent-openapi-gen` to emit OpenAPI JSON
- `openapi-typescript` to generate types

## Usage

```ts
import { SandboxDaemonClient } from "@sandbox-agent/typescript-sdk";

const client = new SandboxDaemonClient({
  baseUrl: "http://127.0.0.1:8787",
  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 });
```
