Authentication Hierarchy

How Nullstack resolves API keys during CLI and launcher execution.

Priority 01

CLI Flag (--api-key)

Highest priority. Explicit key passed directly in the launcher command.

Priority 02

Environment Variable (NULLSTACK_API_KEY)

Used if no CLI flag is provided. Ideal for CI/CD and container workflows.

Priority 03

Stored Login Key (~/.config/nullstack/credentials.json)

Default fallback. Created automatically when running 'nullstack login'.
