API key - E2B Docs

To use the API key, you can either:

Set the API key as the E2B_API_KEY environment variable to avoid passing it each time you create a sandbox.
Or pass it directly to Sandbox.create as shown below:

import { Sandbox } from 'e2b'

const sandbox = await Sandbox.create({ apiKey: 'YOUR_API_KEY' })

from e2b import Sandbox

sbx = Sandbox.create(api_key="YOUR_API_KEY")

Where to find API key

You can get your API key at console. The same API key authenticates both the SDKs and the CLI.
