How to validate email addresses in RapidQL

Our free API to validate e-mail addresses is really easy to use in RapidQL.


Validate e-mail in RapidQL

const RapidQL = require('RapidQL');
let rql = new RapidQL({

    headers : {
      "X-RapidAPI-Host": "",
      "X-RapidAPI-Key": "YOUR-API-KEY"
  ) {

.then((res) => console.log(res))
.catch((err) => console.log(err));

This will return a JSON-array with information about the domain, and if you should block it or not.


You can of course just send it as a regular GET-request to that URL also, in your favorite way, as long as you have the API-key in the header.

You will receive a JSON response, telling you if this is a disposable e-mail to block, or if there are other issues with the domain:


   "valid": true,
   "block": true,
   "disposable": true,
   "domain": "",
   "text": "Disposable e-mail",
   "reason": "Heuristics (4a)",
   "risk": 91,
   "mx_host": "",
   "mx_info": "Using MX pointer from DNS with priority: 0",
   "mx_ip": "",
   "last_changed_at": "2020-06-11T09:56:02+02:00"

This will tell you if you should block the domain or not, and the reason to why the API thinks so (disposable e-mail, etc). You can also see more detailed documentation of the response here.
