I don't think this endpoint is the right place for statistics reports. Since you use it to POST one event at a time, you would expect to GET events with the same level of detail, and that's not very useful for a report. Reports are usually about a combination of a few aspects of a number of events at the same time. e.g. the most popular items in the repository, where we need to facet the view events on item id.

I envision reports will get a dedicated endpoint e.g. /api/statistics/reports that will return data in some json equivalent of a table format

I agree. That was my mistake to leave the endpoint as is. I will change it.
