Documented steps
Install the SDK: Python `pip install e2b-code-interpreter`, JavaScript/TypeScript `npm i @e2b/code-interpreter` (docs: https://e2b.dev/docs/quickstart)
Get an API key from the E2B dashboard (https://e2b.dev/dashboard?tab=keys) and export it as E2B_API_KEY
Create a sandbox: both SDKs use `Sandbox.create()` (JS: `const sbx = await Sandbox.create()`; Python: `sbx = Sandbox.create()`)
Run code: Python `execution = sbx.run_code("print('hello')")`, JS `const execution = await sbx.runCode('print("hello")')` — the string is executed as Python inside the sandbox by default
Read output from `execution.logs` (stdout/stderr) and `execution.results`; check `execution.error` (fields: name, value, traceback) for runtime failures
Kill the sandbox when done with `sbx.kill()` to stop billing, or rely on the timeout
Known gotchas
Timeout units differ by SDK: JS `Sandbox.create({ timeoutMs: 60_000 })` is milliseconds, Python `Sandbox.create(timeout=60)` is seconds — a copy-paste between languages silently gives a 1000x wrong lifetime (https://e2b.dev/docs/sandbox)
The old env var E2B_ACCESS_TOKEN is deprecated: no new tokens after 2026-07-01 and all stop working 2026-08-01 — use E2B_API_KEY (https://e2b.dev/docs/migration/access-token-deprecation)
Sandboxes are billed per second while running; max continuous runtime is 1 hour on Base/Hobby and 24 hours on Pro
