Original Summary

Hey everyone! 👋 Over the past few weeks, I’ve been working on a lightweight, ultra-fast email verification API built with FastAPI and hosted on Render. Most commercial verification services (like ZeroBounce or NeverBounce) are either bloated or ridiculously expensive if you just need fast syntax, DNS/MX record validation, and quick B2B filtering. ### ⚡ Key features: - Sub-20ms latency: In-memory async checks for single and bulk emails. - Batch Endpoint: Validate up to 100 emails in a single POST request. - Smart B2B Filters: Built-in server-side hygiene flags (business_only, exclude_free, no_role_only, disposable_only, etc.). - Zero bloat: Simple, predictable JSON responses. I just published it on the RapidAPI Marketplace. There is a permanent free tier of 100 requests/month so anyone can test it, plug it into a side-project, or run tests against their forms. 🔗 Link to test it on RapidAPI: https://rapidapi.com/albertofigueroam45/api/ultra-fast-email-verification-b2b-lead-hygiene I’d love to get some candid feedback on the response format, latency, or any features/filters you think are missing! Thanks for taking a look! 🙌   submitted by   /u/Unusual_Nobody_106 [link]   [comments]
