BillionVerify
Find the emails. Clean the list. Pay only for answers.
What it does
We rebuilt BillionVerify from the infrastructure up — and added the step before verification. Upload limits are gone: drop in a CSV of any size, close the tab, we email you when it's clean. You only pay for definitive answers — unknown results are free, rechecks free for 24 hours. New Email Finder turns a name and domain into a verified work email, one at a time, in bulk, or by company, and only charges on a match. Real-time API, native MCP server, 20 free credits a day.
The email verification tool built for scale. Real-time SMTP checks, bulk list cleaning, and API with 99.9% accuracy. 600 free credits monthly, plus 20 more…
BillionVerify combines syntax, domain, MX, SMTP, reputation, and risk checks, then returns clear statuses for individual addresses, lists, and API workflows. Validate one email before it enters a lead list, signup flow, or outbound workflow. The result shows status, SMTP verification, MX records, and reputation details in one product surface. Turn large lists into clear validity distribution, status counts, and export-ready segments so sales and marketing teams can remove bad addresses before campaigns launch. Submit email files, estimate processing time, and watch live progress by status while BillionVerify handles the batch verification job in the background.

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
