Here's how to call it from a Strongloop Model with a vow promise

function getGeoWords(lat,lng){
    var deferred = vow.defer();
    var w3wDatasource = Model.app.dataSources.w3w;
    w3wDatasource.geoword(lat, lng,function(err, result) {
         if(result && result[0] && result[0].length === 3) {
           deferred.resolve( {'url':'http://w3w.co/'+result[0].join('.'), 'words': result[0]} );
         } else {
          deferred.reject('No w3w Found');
         }
       });
    return deferred.promise();
  }
