+    "depth" parameter is DEPRECATED. I don't believe it's used but if so, below is the old documenation for it
     The "depth" parameter in the query string indicates how many levels in the category tree to descend.  Default is 2.
     If depth == 0, descends to end of tree

     The "dependents" parameter, if true, includes dependent texts.  By default, they are filtered out.
