I'm using Android, so I can't exactly copy the entire URL string that I'm using, but I'm using:

mClient = new AsyncHttpClient();
mParams = new RequestParams();

        mParams.put(page.toString(), "page"); // where page is an integer that starts at 1, in this case, it's 1
        mParams.put("myApiKey", "api_key");
        String requestUrl = baseUrl + nowPlaying;
        Toast.makeText(mContext, requestUrl, Toast.LENGTH_LONG).show();
        Log.d("TAG", requestUrl);
        mClient.get(baseUrl + nowPlaying, mParams, new JsonHttpResponseHandler() {
  @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
               try {
                   JSONArray moviesJson = response.getJSONArray("results");
                   String jsonString = moviesJson.toString();
                   Toast.makeText(mContext, jsonString, Toast.LENGTH_LONG).show();
                   mMovies = Movie.fromJson(moviesJson);
               } catch (JSONException e) {
                   e.printStackTrace();
               }
           }

           @Override
           public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject jsonObject) {
               Log.d("Failed: ", ""+statusCode);
               Log.d("Error : ", "" + throwable);
           }

In LogCat, I'm getting a 401 error... If you check my account, you'll see what my API key is, so I"m wondering why it's autofailing. I tried using CocoaRest Client with api_key, page as correct parameters and i'm still getting a 401.
