Stop Coupon & Promo Code Stacking Abuse
E-commerce & Retail
The problem
Shoppers create dozens of accounts with plus-aliases and disposable domains to stack first-order coupons and referral discounts.
The VeriShield solution
Canonical normalization collapses alias variants to one identity, and disposable detection blocks burner inboxes before a coupon is ever issued.
How it works
Call /v1/verify during signup. The edge returns disposable status, canonical identity, entropy and domain-age signals as a single 0-100 score, so you can ALLOW legitimate users, CHALLENGE risky ones, and BLOCK fraud before an account is created.
