I have played a little with it.
A short example:

-export([reverse_geocode/0]).
-define(BASE_URL,
"http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/" ++
	    "Locators/ESRI_Geocode_USA/GeocodeServer/reverseGeocode?" ++
	    "location=-117.195681386%2C34.057517097&distance=5&outSR=&f=pjson").

reverse_geocode() ->
    reverse_geocode(?BASE_URL).

reverse_geocode(Url) ->
    {ok, Result} = httpc:request(Url),
    {{_,200,_},_,Body} = Result,
    {_Json} = mochijson2:decode(Body),
    {Data} = proplists:get_value(<<"address">>, _Json),
    Data.
