## About

## What it does
Disposable Email Checker lets you detect whether an email address belongs to a known disposable domain. Send an `email` value and get back the normalized `email`, the `domain`, and a boolean `disposable` flag.

Use it when you need to reduce throwaway signups, filter low-quality leads, or add an extra trust check during account creation. The response is intentionally small and direct, so you can make a yes/no decision without parsing extra metadata.

Because the endpoint works at the domain level, it fits common validation flows where you already have an email address and want to know whether the domain is on a disposable list. If `disposable` is `true`, you can block registration, route the user through additional verification, or mark the record for review.

Disposable Email Checker is a good fit for signup forms, onboarding flows, and lead capture pipelines where disposable addresses create noise or abuse.
