the internal api works well for most of my needs...if it goes unsupported is there any other way to access the same resource?

I'm trying integrating Zendesk with my app , which displays licensing related information for Zendesk. I want to know if there is an api endpoint available for fetching the Zendesk account owner's details like plan type ,payment, renewal date kind of information through api. Thanks in advance.
