## What is E2B?
[E2B](https://www.e2b.dev/) is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our [JavaScript SDK](https://www.npmjs.com/package/@e2b/code-interpreter) or [Python SDK](https://pypi.org/project/e2b_code_interpreter).

## Run your first Sandbox

### 1. Install SDK

```bash
npm i @e2b/code-interpreter
```

### 2. Get your E2B API key
1. Sign up to E2B [here](https://e2b.dev).
2. Get your API key [here](https://e2b.dev/dashboard?tab=keys).
3. Set environment variable with your API key
```
E2B_API_KEY=e2b_***
```     

### 3. Execute code with code interpreter inside Sandbox

```ts
import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
await sbx.runCode('x = 1')

const execution = await sbx.runCode('x+=1; x')
console.log(execution.text)  // outputs 2
```

### 4. Check docs
Visit [E2B documentation](https://e2b.dev/docs).

### 5. E2B cookbook
Visit our [Cookbook](https://github.com/e2b-dev/e2b-cookbook/tree/main) to get inspired by examples with different LLMs and AI frameworks.
