How to use it?

Simple REST API. Here's how it works:

Sign up on Omkar Cloud by visiting this link.
Visit the API Key Page.
Copy your API key.
Make a request with it:

cURL:

curl -X GET "https://whois-api.omkar.cloud/whois?domain=github.com" \
  -H "API-Key: YOUR_API_KEY"

Python:

import requests

domain = "https://github.com"
api_key = "YOUR_API_KEY"

response = requests.get(
    "https://whois-api.omkar.cloud/whois",
    params={"domain": domain},
    headers={"API-Key": api_key}
)
print(response.json())

JavaScript (Node.js axios):

import axios from "axios";

const domain = "https://github.com";
const apiKey = "YOUR_API_KEY";

const response = await axios.get("https://whois-api.omkar.cloud/whois", {
    params: { domain },
    headers: { "API-Key": apiKey }
});
console.log(response.data);

Get structured JSON back and use it:

{
  "domain": "github.com",
  "registration": {
    "registrar": "markmonitor, inc.",
    "whois_server": "whois.markmonitor.com",
    "created_at": "2007-10-09T18:20:50Z",
    "updated_at": "2024-09-07T09:16:33Z",
    "expires_at": "2026-10-09T18:20:50Z"
  },
  "dns": {
    "name_servers": [
      "ns-1283.awsdns-32.org",
      "ns-1707.awsdns-21.co.uk",
      "dns1.p08.nsone.net",
      "dns2.p08.nsone.net",
      "ns-421.awsdns-52.com",
      "dns3.p08.nsone.net",
      "ns-520.awsdns-01.net",
      "dns4.p08.nsone.net"
    ],
    "dnssec_status": "unsigned",
    "dnssec_enabled": false
  }
}

That's it. Domain data in seconds.
