Documented steps
Get an API key from the E2B dashboard (e2b.dev) and export it as E2B_API_KEY (keys start with e2b_).
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
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
Terminate promptly with sandbox.kill() to stop per-second billing; get_info()/getInfo() returns sandbox metadata.
Known gotchas
Timeout units differ by SDK: Python seconds, JavaScript milliseconds — and setting a timeout RESETS the countdown from that moment.
Sandboxes auto-terminate after 300 s unless a longer timeout is set — long tasks silently die at the default.
Billing is per-second while running; killed/paused sandboxes cost nothing. Hobby limits: 20 concurrent sandboxes, 1 creation/sec.
Package names matter: e2b-code-interpreter (Python) / @e2b/code-interpreter (JS), not the older bare 'e2b' package for code execution.
