Obtaining more than 20 results with Google Places API

I want to develop a map application which will display the banks near a given place.

I use the Places library to search and everytime it just return 20 results. What should I do if I want more results?

Answer*

Here's code sample that will look for additional results

using System;
    using System.Collections.Generic;
    using System.Net.Http;
    using System.Web.Script.Serialization;
    
    
    namespace ConsoleApplication1
    {
        class Program
        {
            static void Main(string[] args)
            {
                var url = $"https://maps.googleapis.com/maps/api/place/nearbysearch/json?location={args[0]}&radius={args[1]}&type=restaurant&keyword={args[2]}&key={args[3]}";
    
                dynamic res = null;
                var places = new List<PlacesAPIRestaurants>();
                using (var client = new HttpClient())
                {
                    while (res == null || HasProperty(res, "next_page_token"))
                    {
                        if (res != null && HasProperty(res, "next_page_token"))
                        {
                            if (url.Contains("pagetoken"))
                                url = url.Split(new string[] { "&pagetoken=" }, StringSplitOptions.None)[0];
                            url += "&pagetoken=" + res["next_page_token"];
    
                        }
                        var response = client.GetStringAsync(url).Result;
                        JavaScriptSerializer json = new JavaScriptSerializer();
                        res = json.Deserialize<dynamic>(response);
                        if (res["status"] == "OK")
                        {
                            foreach (var place in res["results"])
                            {
                                var name = place["name"];
                                var rating = HasProperty(place,"rating") ? place["rating"] : null;
                                var address = place["vicinity"];
                                places.Add(new PlacesAPIRestaurants
                                {
                                    Address = address,
                                    Name = name,
                                    Rating = rating
                                });
                            }
                        }
                        else if (res["status"] == "OVER_QUERY_LIMIT")
                        {
                            return;
                        }
                    }
                }
            }
    
            public static bool HasProperty(dynamic obj, string name)
            {
                try
                {
                    var value = obj[name];
                    return true;
                }
                catch (KeyNotFoundException)
                {
                    return false;
                }
            }
        }
    }

Hope this saves you some time.
