Use this Free API is as easy as hitting a URL.

DeBounce provides a free & powerful API endpoint for checking a domain or email address against a realtime up-to-date list of disposable domains.
CORS is enabled for all originating domains, so you can call the API directly from your client-side code.

Rate Limiting

The number of calls per day and validation speed are limited for the free disposable detector API. For security reasons, we cannot share this information. If you have normal usage, you never hit these numbers.
