Fetch a SoundCloud API key without owning an application

Fetch a SoundCloud API key without owning an application

This script allows you to retrieve an API key without having to create a resource. Be careful though, the site can change suddenly, so keep this in mind.

There are two versions of this script, one without dependencies and one using node-fetch

getSoundCloudAPIKey01.js

// With external dependency ( node-fetch )

// ██████ Dependency █████████████████████████████████████████████████████████

// —— A light-weight module that brings Fetch API to Node.js.
const fetch = require( "node-fetch" );

// ██████ | ███████████████████████████████████████████████████████████████████
