## 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 ``` pip install 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 ```py from e2b import Sandbox with Sandbox.create() as sandbox: result = sandbox.commands.run('echo "Hello from E2B!"') print(result.stdout) # Hello from E2B! ``` ### 4. Code execution with Code Interpreter If you need [`run_code()`](https://e2b.dev/docs/code-interpreting), install the [Code Interpreter SDK](https://github.com/e2b-dev/code-interpreter): ``` pip install e2b-code-interpreter ``` ```py from e2b_code_interpreter import Sandbox with Sandbox.create() as sandbox: execution = sandbox.run_code("x = 1; x += 1; x") print(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.
