+Innertube is an API used across all YouTube clients, it was [made to simplify](https://gizmodo.com/how-project-innertube-helped-pull-youtube-out-of-the-gu-1704946491) the internal structure of the platform and make it easy to push updates. This library takes advantage of that API, therefore providing a simple & efficient way to interact with YouTube programmatically.

+And big thanks to [@gatecrasher777](https://github.com/gatecrasher777/ytcog) for his research on the workings of the Innertube API!
