isDisposable

What it does

Fake signups cost SaaS companies real money — AI credits burned, trials abused, metrics inflated. isDisposable catches them before they enter. Three detection layers: 160K+ domain blocklist, real-time DNS/MX fingerprinting that catches new disposable services, and risk scoring 0-100. One line to integrate: isDisposable(email). Free npm package forever. Pro API from $9/mo adds a dashboard showing exactly how much money you're saving. Paste our AI prompt into Cursor — done in 60 seconds.
