API to pull in all data on all sites and users in Matomo

I have multiple servers that have multiple dashboards on each. I am tracking usage data, but would like to pull all the data down to show individual dashboard metrics. The list of APIs is AWESOME, but instead of making multiple API calls to get all the data I need, I’d like to do one call and get everything. I can’t seem to find an API that does this. Can someone point me to this? Thanks!!
