Is there any documentation around the Accounts API?

Hello !

I was looking at the API for Zendesk Support and could find only the documentation about the "Account Settings" endpoint. I found in one of the posts that there is an account API but it is undocumented.

https://develop.zendesk.com/hc/en-us/community/posts/360001650407/comments/360004730693

Is this documented anywhere currently? I am asking because the comment is about 2 years. old. 

Any information in this regard would be appreciated.

Thanks in advance!
