I Built a Free Email Verification API (100 calls/day)

I built a simple email verification API using FastAPI + Python.

Why? Because email validation is crucial for any SaaS product,
but most services charge per API call.

Features:
• RFC 5322 format validation
• MX record checking
• 100 free calls per day
• REST API, 10ms response time

Would love feedback from the dev community!
