Developer API Integration Guide

Simple REST JSON API and Port 43 TCP Daemon code examples for your applications.

REST API (HTTP / JSON)

Query WHOIS and RDAP expiration dates over HTTP REST endpoint.

// cURL Terminal Request
curl -H "X-API-Key: sq_live_YOUR_KEY" \
  "https://whois.squarecomp.uk/api/whois/google.com"

// Node.js Fetch Example
const res = await fetch('https://whois.squarecomp.uk/api/whois/example.pizza', {
  headers: { 'X-API-Key': 'sq_live_YOUR_KEY' }
});
const data = await res.json();
console.log(data.expiration_date);

Port 43 TCP WHOIS Daemon

Query standard RFC 3912 raw WHOIS plain text over TCP port 43.

# Linux Terminal CLI
whois -h whois.squarecomp.uk handle.monster

# Python Socket Example
import socket
s = socket.create_connection(('whois.squarecomp.uk', 43))
s.sendall(b'squarecomp.uk\r\n')
print(s.recv(4096).decode('utf-8'))
