API Keys, Environment Variables, Costs, and Safe Local Setup

By the end of this module you can set up keys and environment variables safely, estimate what a feature will cost per call, and avoid the mistake that puts a secret in version control.

Units

1. Unit 02.00: Keys in the environment, never in the file
2. Unit 02.01: The key that reached your git history
3. Unit 02.02: Costing a feature before you build it
4. Unit 02.03: A spend ceiling your code enforces
5. Unit 02.04: A local setup someone else can reproduce
