My IP

My IP is a lightweight Cloudflare Worker that displays the visitor's public IP address and, when available, the proxy IP address detected from request headers. It provides a simple browser interface with click-to-copy support and a small JSON API for programmatic use.

Live Demo

The application is available at:

Features

• Displays the visitor's public IP address.
• Detects and displays a proxy IP address when request headers indicate proxy usage.
• Copies an IP address to the clipboard with one click.
• Exposes a JSON endpoint for direct IP lookup.
• Runs at the edge on Cloudflare Workers.

API

GET /api/ip

Example response:

{
  "myIp": "203.0.113.10",
