Documented steps
Install the SDK: Python 'pip install e2b' (core) or 'pip install e2b-code-interpreter' (adds run_code); JS/TS 'npm i @e2b/code-interpreter'.
Get an API key at https://e2b.dev/dashboard?tab=keys and set it as the E2B_API_KEY environment variable in your process (e.g. .env: E2B_API_KEY=e2b_***).
Python: 'from e2b import Sandbox' then 'with Sandbox.create() as sandbox: ...'. Code-interpreter: 'from e2b_code_interpreter import Sandbox'; 'with Sandbox.create() as s: ...'.
Use the returned object to run commands (sandbox.commands.run), run code (run_code), or manipulate files (sandbox.files) inside the running Linux sandbox.
Known gotchas
A brand-new sandbox runs a stock Linux (LTS 6.1 kernel) environment with only the base image; commonly needed packages must be installed per-sandbox unless you use a custom template.
Sandbox.create() accepts template, timeout, envs, metadata, secure, and allow_internet_access params; default timeout is 300s and internet access defaults to True.
Sandbox processes are ephemeral: by default the sandbox is killed when the with-block exits or its timeout lapses (see auto_pause for the exception).
The E2B API key starts with e2b_ and must be treated as a secret; never log it.
