❌ No-as-a-Service (Python)

Ever needed a graceful way to say "no"?
This tiny API returns random, generic, creative, and sometimes hilarious rejection reasons , perfectly suited for any scenario: personal, professional, student life, dev life, or just because.

Built for humans, excuses, and humor.

This is a Python port of the original no-as-a-service project.
