✨ Features
- Lightweight HTTP server running only on localhost providing your coordinates
- Client-side only - no server-side components needed
- Works in singleplayer and multiplayer
- Mod menu integration allowing you to enable/disable the API, change its port, and configure requests with or without an
Originheader

The API is read-only and only accepts loopback connections such as 127.0.0.1 and ::1.
From Mod Menu, you can configure:
- Whether the API is enabled
- Which port it listens on (default:
25565) - How requests without a CORS
