How to find the top improving identifiers for a taxon?

Is there a way to find, say, the top 50 improving identifiers for a particular taxon? Not leading, supporting, or maverick.


It seems to be possible using the inat api. The GET/identifications/identifiers method “returns creators of identifications matching the search criteria and the count of matching identifications, ordered by count descending”. So for example a url to get the top 50 improving identifiers for Pieris brassicae would be:

The results are returned as json - which displays quite nicely in Firefox, but I’m not sure about other browsers. I don’t think there’s any way to adapt this method to get formatted output similar to the identifications page, though.

here’s something that might help to display that json in a format that’s a little more friendly. just copy the code below into a text / html / code editor and save it as an .html file. then open up the file in any browser. feel free to modify as you like.
