Help Creating API to Share Power BI Data

[JohnJ404]

Hi everyone,
 
I hope I'm posting on the right forum. I have a question I'm hoping someone can assist wth.
 
We have created a dashboard which we regularly update. We have a client who would like to access some of the underlying data from our Power BI dashboard. They use transformers and hydrator integration in their systems so that our server will not be hit every time a reader hits one of our pages with your info embedded on it.  This way they act as buffers between their server and our Power BI data and they’d only need to hit your system once a day rather than hundreds+ times per day. 
 
Would anyone have any insight on how we might be able to set this up?
 
Thanks for your feedback.
