## About

## What it does
Email Validator checks whether an email address is valid and deliverable. Send an `email` address in the request body, and you get back a boolean `data` value indicating whether it passes verification.

Use `disposable_checks` when you want to reject known disposable domains before MX verification. It defaults to `true`, so you can catch throwaway addresses without adding extra logic in your app. The response stays simple: `true` or `false`.

This is useful anywhere you need to screen signups, clean lead lists, or reduce bounce rates before sending messages. Add it to registration flows, CRM imports, newsletter subscriptions, or contact forms when you want a fast yes-or-no check on an address.

## Usage

Authenticate with an ApyHub API key in the `apy-token` header.
