<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Use new connect API for JS/Python SDKs to connect and only extend
(never shorten) running sandbox timeouts, with updated types/docs and
tests.
>
> - **SDKs**:
> - **JS**:
> - Replace `resume`/`setTimeout` flow with `SandboxApi.connectSandbox`
calling `POST /sandboxes/{sandboxID}/connect`.
> - Update `Sandbox.connect` (static/instance) to use returned
`sandboxDomain`, `envdAccessToken`, `envdVersion`.
> - Redefine `SandboxConnectOpts` to include `timeoutMs` that only
extends existing timeout.
> - **Python (async/sync)**:
> - Introduce `_cls_connect` using `post_sandboxes_sandbox_id_connect`
with `ConnectSandbox`; return `Sandbox` model.
> - Update `connect` methods to use API response for
domain/token/version; remove extra info fetch.
> - Docstrings clarify timeout only extends for running sandboxes.
> - **Tests**:
> - Add cases ensuring connect does not shorten timeout and does extend
when longer (JS, async Python, sync Python).
> - Preserve error on connecting to non-running sandbox.
> - **Meta**:
> - Changeset: minor releases for `@e2b/python-sdk`, `e2b`, and
`@e2b/cli`.

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.
Run your first Sandbox
1. Install SDK
pip install e2b-code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
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.
