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?
