Icanhazip

API

Simple API to retrieve your public IP address

Overview

Icanhazip is a lightweight RESTful API for developers to get their public IP address quickly. Its core endpoint is a GET request to the root URL, returning the client’s IPv4/IPv6 address in plain text by default. Adding .json to the endpoint (e.g., /json) provides structured JSON with IP type metadata. Ideal use cases include network debugging, verifying VPN/proxy status, automating IP checks in scripts, or integrating basic IP detection into apps. It prioritizes speed and simplicity with minimal latency.

Example Integration (JavaScript)

script.js JS


fetch('https://major.io/icanhazip-com-faq/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
