Scheduled export of a filtered list of accounts to be used in another system

Sugar Professional 7.6.0

I have been asked to created a scheduled export of a couple of fields from accounts to be imported (automatically) into another system.  The format that would be best would be a json list. 

I have read about the export api, but I'm not sure how to incorporate that into the schedulers.

Also has anyone worked with this kind of event before?  Any advice on how to add a location to where the file exports to?
