Export data, requests to Power BI and payment

Hi!

We plan to collect data by pulling it out of power BI and for that we plan to take it out of the json that comes to the site. On the site, reports are embedded through Power BI Embedded. And on this occasion we have a few questions:
1. How is each request we make evaluated? How will each request be paid (one report - different filters)?
2. Is it correct to do so? Is there an alternative?
