Is there any way to retrieve Top identifier and top observer for a taxon through the API? At first glance, I don’t see it as part of the JSON for https://api.inaturalist.org/v1/docs/#!/Taxa/get_taxa_id but perhaps it’s hiding under some other entity? Thanks.
Check out the observers and identifiers endpoints under Observations https://api.inaturalist.org/v1/docs/#/Observations. They’ll accept a taxon_id parameter as well as a bunch of others if you wanted to filter by quality grade, place, etc
there’s been some discussion about whether the identifiers endpoint under Observations properly returns the top identifiers for a particular taxon. (see Link to top identifiers of that taxon, not observations of that taxon - Feature Requests - iNaturalist Community Forum for one of the several discussions on this topic.)
the identifiers endpoint under Identifications provides an alternative list of identifiers that some might find preferable.
