spotilocal

Unofficial api for Spotify's local web server.

How it works

It uses the same method as https://developer.spotify.com/technologies/widgets/spotify-play-button/ does. Basically Spotify desktop runs a web server on 127.0.0.1 that can accept specific commands and even open Spotify client itself.

Spotify domain spotilocal.com that simply points to 127.0.0.1. Apparently in order to bypass browser's limitation of amount of concurrent connection to the same domain they use randomly generated subdomains of spotilocal.com.
