Using the Numverify API with JavaScript

The Numverify API is a public API that allows you to easily verify phone numbers and retrieve information about them. In this tutorial, we will explore how to use the Numverify API with JavaScript.

Getting started

First, you need to sign up for a free API key from Numverify. Once you have your API key, you can make requests to the Numverify API using JavaScript.

Making requests to the Numverify API

To make requests to the Numverify API, you can use the built-in fetch function in JavaScript. Here is an example code snippet that shows you how to make a request to the Numverify API and retrieve information about a phone number:

fetch('http://apilayer.net/api/validate', {
    method: 'POST',
    body: JSON.stringify({access_key: YOUR_API_KEY, number: PHONE_NUMBER}),
    headers: {'Content-type': 'application/json'}
})
.then(response => response.json())
.then(data => console.log(data))
.catch(err => console.error(err));

In the above code, replace YOUR_API_KEY with your actual API key, and PHONE_NUMBER with the phone number you want to verify.

Handling the response

Once you make a request to the Numverify API, you will receive a response in JSON format. Here is an example response:

{
    "valid": true,
    "number": "14158586273",
    "local_format": "4158586273",
    "international_format": "+14158586273",
    "country_prefix": "+1",
    "country_code": "US",
    "country_name": "United States of America",
    "location": "San Francisco",
    "carrier": "AT&T Mobility LLC",
    "line_type": "mobile"
}

You can access the fields in the response just like you would with any JSON object in JavaScript. For example, you can access the country code like this:

console.log(data.country_code);
