Introduction
Stop free trial abuse and repeat credit claims with one API call.
AbuseZero checks every sign-up and benefit claim before you hand anything out. You send what you know about the person, and we return a risk score and a decision based on the rules you set.
How it works
- A user starts a trial, redeems a coupon or claims credits.
- Your backend calls
POST /v1/checkswith their email, IP and device. - AbuseZero compares them against benefit history and returns
allow,reviewordeny. - You grant the benefit, ask for more verification, or block it.
