Environment Variables

Environment Variables are the recommended home for secrets in Brevvie Python + AI — Section 4: APIs, Postman & Calling the Web. The source explicitly says API keys should never live in committed source code.

Core pattern from the source

• put secrets in .env
• add .env to .gitignore
• load them into Python before making API calls
• read them through os.environ
• optionally use Python Dotenv to load .env automatically in local development

Why it matters

This is baseline operational hygiene for any code that talks to paid or rate-limited external services.
