Read the docs

const data = {
  "email": "john.doe@gmial.com"
};

const response = await fetch('https://api.emailvalidationapi.io/v1/validate', {
  method: "POST",
  body: JSON.stringify(data),
  headers: {"Content-type": "application/json; charset=UTF-8"}
});

console.log(response.json());

How it works.

The API checks whether an email address exists in three simple steps.

Email address format

The API starts with a simple check. Is the input an actual email address? It checks if the syntax complies to RFC 5322, like if it contains an @.

Domain validation

After the format check, the API checks if the domain is valid, whitelisted or blacklisted. Also, it checks whether the domain can receive emails or not.

Smart suggestion

If the email address is invalid, the API will search for a valid alternative. You can use this to inform your user: "Did you mean john.doe@gmail.com?"
