There is finally a public API! http://forum.counterpointapp.org/https://counterpointapp.herokuapp.com/#api-Counterpoints_Public. There is also a public forum to report issues: http://forum.counterpointapp.org/
Looks like first you would grab the counterpoint ID from here: https://counterpointapp.herokuapp.com/api/v1/counterpoints
EERC is counterpoint_id 606. Could select by bounding box (lat/long) too. This includes a list of counts (just labeled “id”) but no actual counts, so you could do time/date collection stat comparisons from there as well.
Then you can pull up actual counts from https://counterpointapp.herokuapp.com/api/v1/counterpoints/606 where the counterpoint_id is named at the end. This gives you a list of counts, including data.
It looks like minutes start/end on the second that the count was started, so aggregation by minute (not second) should be used.
It looks like minutes without data are excluded, e.g. no 12:51:52 minute is included here (EERC 606):
