Install

Steel provides SDKs for Node.js, Python, and other languages, plus a CLI for quick tasks.

Node.js SDK

npm install steel-sdk

Requires Node.js 18+. The SDK includes TypeScript types out of the box.

Python SDK

pip install steel-sdk

Requires Python 3.8+.

CLI (optional)

The Steel CLI lets you run scrape and screenshot commands without writing code:

curl -sSf https://setup.steel.dev | sh

API Key

All SDK and CLI calls require a Steel API key. Sign up at https://steel.dev/ and set the key as an environment variable:

For the Merlino fleet the key is stored under STEEL_API_KEY in MASTER_API_KEYS.env.
