I built Guardient, a simple API to help developers stop fake, abusive, and risky users before they get into your app.

It checks things like:

Temporary/disposable emails

VPN and proxy IPs

Temporary/burner phone numbers

You send a request from your backend, and it returns a trust score with reasons. You decide what to do with that info—block, flag, or allow.

No cookies, no client-side scripts—just a clean, server-side API.

I’m 18 and built this out of personal need after getting hit with fake signups and spam in my own projects. Would really appreciate any feedback or thoughts!
