Documented steps

  1. Get an API key from the E2B dashboard (e2b.dev) and export it as E2B_API_KEY (keys start with e2b_).
  2. Install the SDK: Python 'pip install e2b-code-interpreter', JavaScript 'npm i @e2b/code-interpreter'. No raw REST API is documented — access is SDK-only. Docs: https://e2b.dev/docs/quickstart
  3. Create a sandbox: Python 'sandbox = Sandbox.create()' / JS 'const sandbox = await Sandbox.create()'.
  4. Execute code: Python 'sandbox.run_code(code)' / JS 'await sandbox.runCode(code)' — returns stdout, stderr, and rich results.
  5. Manage lifetime: default timeout is 5 minutes; extend with set_timeout(seconds) (Python) or setTimeout(ms) (JS). Max runtime 1 hour on Hobby, 24 hours on Pro. Docs: https://e2b.dev/docs/sandbox
  6. Terminate promptly with sandbox.kill() to stop per-second billing; get_info()/getInfo() returns sandbox metadata.
