I built a free email verification API, feedback welcome!

Got tired of fake signups on my projects, so I built a small API that validates emails in real-time. Checks format, MX records, disposable domains, and role accounts — returns a clean JSON verdict.

Free tier is 50 requests/month. Built with Node + Express, deployed on Vercel, listed on RapidAPI.

Two endpoints:

  • GET /validate?email=test@example.com
  • GET /validate/bulk?emails=email1,email2,... (up to 20)

Would love honest feedback — what's missing, what would make it actually useful in your projects?
