Installation & Authentication

Installation

Install the Simplex Python SDK and CLI from PyPI:

pip install simplex

Requires Python 3.9 or higher.

After installation, both the Python SDK (from simplex import SimplexClient) and the simplex CLI command are available.

Authentication

simplex login

This opens a browser-based OAuth flow. Credentials are saved to ~/.simplex/credentials and used automatically by the SDK and CLI. If you are working in a headless environment, use the --api-key flag:

simplex login --api-key YOUR_API_KEY

Quick verification

After installing and configuring authentication, verify that everything is working:
