Library api endpoint exist?

Does anybody know if a library endpoint exists for community made libraries?

There is an undocumented endpoint but I don't recommend using it as it probably violates the User Agreement. How do you intend to use it?

I think this would be useful for creating libraries, updating libraries or downloading libraries. Particularly if these are personal games (such as OTB) or repertoires.

Creating and updating will likely never be available since it's interactive. But for downloading particular libraries like "best games" or repertoire it's certainly helpful. There is an undocumented endpoint and I don't feel comfortable sharing it but it's pretty easy to find. I recommend only personal use for chess purposes (even this can be not allowed) and not community/public use due to the User Agreement
