Dropbox and API's call limit

[KURUMASPORTSA]

Hi.

I have encountered a problem in the dropbox API.
With the new dropbox contract (Dropbox Business Advanced), they limit the calls to the API to 25,000.
I tried to synchronize small and large files, but in the best of cases, the API calls are finished in four days. And they are not renewed until the 1st of the following month.
There was a case in which they were finished just by synchronizing the folder structure.

My question is:
Who has developed the dropbox API for NETGEAR ReadyNas?
Could it be updated to reduce API calls?

Now it does not suppose any venficio to make backup through this application.

Also know if there is something that I can do.

Thank you.
