WHOIS Lookup is a domain WHOIS API that reads the registry's RDAP or WHOIS record for any domain and returns the registrar, creation and expiry dates, nameservers, EPP status codes explained in plain English, transfer-lock and privacy flags, the registrant country where it is published, and domain age in days and years.
The WHOIS Lookup API provides a simple, reliable way to integrate whois lookup functionality into your applications. Built for developers who need production-ready whois lookup capabilities without the complexity of building from scratch.
Quick Start
Using JavaScript
async function callWHOISLookupAPI() {
try {
const params = new URLSearchParams({
domain: 'myspace.com'
});
const response = await fetch(`https://api.apiverve.com/v1/whoislookup?${params}`, {
method: 'GET',
headers: {
'x-api-key': 'YOUR_API_KEY_HERE'
}
});
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error:', error);
}
}
callWHOISLookupAPI();Using cURL
curl -X GET "https://api.apiverve.com/v1/whoislookup?domain=myspace.com" \
-H "x-api-key: YOUR_API_KEY_HERE"Get your API key: https://apiverve.com
