Show HN: Guardient – An API to block fake users (temp emails, VPNs, burner phone

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!

The thing with preventing this kind of abuse is that its an arm's race between abusers and developers, so I would worry that a small org will have trouble keeping up.

It's mostly targeted against fake users trying to use the free trial. And although it could be hard to keep up, we also use several open source projects to keep up with the demand. And very soon we are planning to add features like fingerprinting (no-cookies) that could already eliminate any normal/non-technical user!
