What is the Power BI API request limit? (Status =429, 'Too many requests')

Hi,

I'm trying to use the Power BI api to programatically change the dataset parameters of an embedded report. I'm just writing the script so not sending many requests yet, but already hit a limit. Is my plan dead in the water?

request is to update paramters in group:
