Overview

Disify is a free, no-auth API that checks whether an email address or domain belongs to a known disposable or temporary email service. It helps protect sign-up forms and contact forms from throwaway addresses with a simple GET request. No API key is required, making it the fastest way to add disposable email detection to your app.

Beginner Tip

You can check an email in one GET request with no setup at all — just replace the email in the URL path and you get a JSON response instantly. Cache results for the same domain to avoid redundant requests, since disposable domain status rarely changes.
