API Example Code (JavaScript)
The following example uses the fetch function to request WHOIS information of the domain google.com in JSON format.
const apiKey = 'YOUR_API_KEY';
const domain = 'google.com';
const format = 'json';
fetch(`https://www.ip2whois.com/developers-api/${format}?apiKey=${apiKey}&domain=${domain}`)
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));
Similarly, you can request WHOIS information of an IP address by setting the ip parameter instead of domain.
const apiKey = 'YOUR_API_KEY';
const ip = '104.198.14.52';
const format = 'json';
fetch(`https://www.ip2whois.com/developers-api/${format}?apiKey=${apiKey}&ip=${ip}`)
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));
Note
You need to replace the YOUR_API_KEY with your actual API key provided by IP2WHOIS.
