What is the Affirmations.dev API?

Affirmations.dev is a free, key-free API that returns a random positive affirmation as a JSON object with a single `affirmation` field.

This is about as small as a useful API gets: one endpoint, no parameters, one field. It serves short positive statements intended for wellbeing and mindfulness applications.

The minimal surface makes it a good teaching example, and a genuinely practical one for daily-prompt features where you want fresh copy without writing and maintaining it yourself.
