Matlab Google Street View and Direction API

Google API.m

origin='Madison,Chicago,IL';
destination='N+Michigan+Ave,Chicago,IL';

url1=['https://maps.googleapis.com/maps/api/directions/json?origin=' origin '&destination=' destination '&sensor=false&key= XXXX&departure_time=1343641500&mode=driving'];
direction=urlread(url1);
d=parse_json(direction);
steps=d{1}.routes{1}.legs{1}.steps;
[startpoints,endpoints]=cellfun(@parsecoord,steps);



for i=1:numel(steps)  % For each step, find the midpoint and save the street view image
    sp=startpoints(i);
    spLat=sp.lat;
    spLong=sp.lng;

    ep=endpoints(i);
    epLat=ep.lat;
    epLong=ep.lng;

    mpLat=(spLat+epLat)/2;
    mpLong=(spLong+epLong)/2;
    %directiondegree=azimuth(spLat,spLong,epLat,epLong);  % calculate the azimuth,i.e. the direction of car
    directiondegree=0;
    roadLat=mpLat;
    roadLong=mpLong;
    heading=directiondegree;
    url=['http://maps.googleapis.com/maps/api/streetview?size=640x640&location=' num2str(roadLat) ',' num2str(roadLong) '&sensor=True&key=XXXX&heading=' num2str(heading)];
    filename=[num2str(i) '_test.jpg'];
    urlwrite(url,filename);
    %b=imread(filename);
    %image(b)
end

Could you please guide me to change this code to use Google Translation API , to translate text using that API during MATLAB?
