Domain WHOIS API: Get Registration and Expiry Data in One Call

#api #security #devtools

Most businesses and security teams need domain information — but WHOIS lookups are either slow, outdated, or behind paywalls.

I built Domain WHOIS API — instant access to registration data, expiry dates, nameservers, and IP addresses for any domain.

What it does

Single endpoint: POST /whois

Returns:

Registrar name
Creation date
Expiration date (+ days until expiry)
Last updated date
Domain status
Nameservers
Country
IP address

Quick start

Python

import requests

url = "https://domain-whois-lookup.p.rapidapi.com/whois"
headers = {
    "X-RapidAPI-Key": "YOUR_KEY",
    "Content-Type": "application/json"
}
payload = {"domain": "github.com"}

r = requests.post(url, json=payload, headers=headers)
print(r.json())
