<!-- CURSOR_SUMMARY --> > [!NOTE] > **Medium Risk** > Changes public error/exception types in both JS and Python SDKs by introducing new subclasses and remapping 404/NotFound conditions, which may affect downstream error handling despite deprecation shims. > > **Overview** > **Distinguishes “sandbox not found” from “file/directory not found” across the SDKs.** Adds `FileNotFound*` and `SandboxNotFound*` error/exception types (with `NotFound*` marked deprecated) and updates sandbox lifecycle APIs to throw `SandboxNotFound*` for missing/non-running sandboxes. > > Refactors envd HTTP/RPC error handling in both JS and Python to support overridable status/code→error maps, and wires filesystem operations to map 404/`NotFound` into `FileNotFound*`. Tests are updated accordingly, and patch changesets are added for both packages. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 73da92694c02f71355b1f8625845c82865bf3b1d.

What is E2B?
E2B 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 or Python SDK.
Note
This repository contains the core E2B SDK that's used in our main E2B Code Interpreter SDK.
Run your first Sandbox
1. Install SDK
JavaScript / TypeScript
npm i @e2b/code-interpreter
Python
pip install e2b-code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
JavaScript / TypeScript
import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()
await sandbox.runCode('x = 1')
const execution = await sandbox.runCode('x+=1; x')
console.log(execution.text) // outputs 2
Python
from e2b_code_interpreter import Sandbox
with Sandbox.create() as sandbox:
sandbox.run_code("x = 1")
execution = sandbox.run_code("x+=1; x")
print(execution.text) # outputs 2
4. Check docs
Visit E2B documentation.
5. E2B cookbook
Visit our Cookbook to get inspired by examples with different LLMs and AI frameworks.
Self-hosting
Read the self-hosting guide to learn how to set up the E2B infrastructure on your own. The infrastructure is deployed using Terraform.
