CLI Setup

Most CLI tools need an API key, Base URL, and model ID. Environment variable names and wire protocols differ between tools, so one configuration cannot be copied unchanged everywhere.

Check your environment

node --version
npm --version

Verify that the CLI starts before changing its API configuration. Use a separate key for each tool so usage is easy to identify and access can be revoked independently.
