## 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) or [Python SDK](https://pypi.org/project/e2b). ## Run your first Sandbox ### 1. Install SDK ```bash npm i e2b ``` ### 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. Start a sandbox and run commands ```ts import Sandbox from 'e2b' const sandbox = await Sandbox.create() const result = await sandbox.commands.run('echo "Hello from E2B!"') console.log(result.stdout) // Hello from E2B! ``` ### 4. Code execution with Code Interpreter If you need [`runCode()`](https://e2b.dev/docs/code-interpreting), install the [Code Interpreter SDK](https://github.com/e2b-dev/code-interpreter): ```bash npm i @e2b/code-interpreter ``` ```ts import { Sandbox } from '@e2b/code-interpreter' const sandbox = await Sandbox.create() const execution = await sandbox.runCode('x = 1; x += 1; x') console.log(execution.text) // outputs 2 ``` ### 5. Check docs Visit [E2B documentation](https://e2b.dev/docs). ### 6. 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.
