[API-users] How to query genus names with the GBIF API

Hello to all list members,

I'm new on this list and also new to the GBIF API. I'd like to get a list of all the genus names occuring in the GBIF database. After several hours of trying with the API, and no success, I found this mailing list. I hope that API guru members on the list can show me the right way or tell if this is not possible at all.

Thank you in advance.
