There isn’t any of the insights data available through a public API, but seems like a reasonable feature to request.
In the mean time, you could use some of the public API to re-create that data collection and aggregation. For example, if you used the pipeline monitoring API you could figure out how many pipes were executed and how many documents were processed. The activity API could be used to figure out how many people had logged in, etc…
But I’d recommend waiting for us to expose the insights data through a public API.
