About

The Validate Email DNS API allows you to verify email domains, detect disposable emails, and prevent invalid email addresses from entering your system. Unlike regular expressions that only check email format, this API confirms whether a domain can actually receive emails, helping reduce bounces and protect your sender reputation.
Ideal for email marketing platforms, SaaS applications, CRM systems, and user registration workflows, it improves email deliverability, data quality, and user experience by providing instant feedback on mistyped or temporary emails.
Try the Validate Email DNS API in the playground for free, enhance email validation, and ensure accurate, reliable communication with a single API call.

Authentication

All API requests to ApyHub services need to be authenticated. Currently we support tokens or basic authentication mechanisms. You can generate and view your existing credentials from your workspace settings (on the left side of the navbar) and go to “API Keys".
Points to note:
  • Credential secrets are generated on the fly and are not stored in plain text, so on generating a credential please save the secrets somewhere safe.
  • Use the apy-token as the header parameter to pass the token.
  • Use the Authorization header to send the basic authentication credentials.
