Mega API hub - 118 endpoints covering social media, finance, sports, AI, e-commerce, and more
Output
Returns a validation result indicating whether the email address is properly formatted, whether the domain exists and can receive mail, whether it is a known disposable or temporary email, and an overall deliverability assessment.
Example use cases
Pre-signup email verification
“Before I create an account for this user, can you verify that their email address sarah.jones@gmail.com is valid and actually exists so we don't end up with a junk entry in our database?”
CRM data hygiene check
“I have an email address I'm about to add to my CRM — can you validate that contact@acmecorp.io is properly formatted and that the domain can receive mail?”
Catch disposable emails at registration
“Someone just signed up with the email throwaway123@mailinator.com — can you check if this is a real, non-disposable email address I should trust?”
