Authentication - Collinear AI

All API requests require an API key passed via the API-Key header.

API-Key: <your-api-key>

Obtaining a Key

Via the CLI:

simlab auth login

This opens platform.collinear.ai where you can find your key under Developers → API Keys. The key is stored in ~/.config/collinear/config.toml. Or set it as an environment variable:

export COLLINEAR_API_KEY="<your-api-key>"
