Overview
Cloudmersive Validate is a comprehensive validation API that can verify email addresses, phone numbers, VAT numbers, and domain names in a single platform. It combines syntax checks with live DNS and SMTP lookups for accurate real-world validation. A good choice when you need multi-type validation without integrating separate APIs.
Beginner Tip
The free tier gives you 800 API calls per month across all Cloudmersive APIs — start with email validation as it is the most commonly needed feature. Use the /validate/email/address/full endpoint for the most complete check, including disposable detection and SMTP verification.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
