Get stock quotes of NSE and BSE using web-service and parse it using json [closed]

Answer 1

Google provide a free web services for NSC and BOM data.

https://finance.google.com/finance?q=NSE:KELLTONTEC&output=json

For google web service NSE data- https://finance.google.com/finance?q=NSE:KELLTONTEC&output=json

For google web service BSE (BOM) data- https://finance.google.com/finance?q=BSE:KELLTONTEC&output=json

In PHP

$bse = file_get_contents("https://finance.google.com/finance?q=BSE:KELLTONTEC&output=json");
$split_slash= str_replace('//','',$bse );
$split_data = stripslashes(html_entity_decode($split_slash));
$data = json_decode($split_data);
$equity = $data[0]->l;
print_r($data[0]->l);

Its return BSE data

Answer 2

For a free service you can call google finance web services or yahoo finance web services, but both are deprecated but are still working.

http://finance.yahoo.com/webservice/v1/symbols/IDFC.NS/quote?format=json&view=detail

in above URL: IDFC is the symbol of security .NS stands for NSE

For BSE just modify NS to BO

for google web service: NSE: http://finance.google.com/finance/info?client=ig&q=NSE:DHFL

for BSE just modify NSE to BOM

Just copy pate above links in a browser to see json output.

Answer 3

Please go to this GitHub library. It will surely help.

Currently it gives live stock from the official NSE site.

This services will give you a json response, you can parse this JSON to get the appropriate value, by just replacing the symbol with a valid NSE code.

Answer 4

If you want to fetch the data from NSE web service, then below is the link:

http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=dhfl

But I'm not sure whether you can use this link or not for non commercial as well as commercial purpose.

As the site has been updated and old site is no more working, updating answers with new updated links:

Equity link - https://www.nseindia.com/api/quote-equity?symbol=DHFL&section=trade_info

Derivatives link: https://www.nseindia.com/api/quote-derivative?symbol=RELIANCE

I'm not sure whether you can use this link or not for non commercial as well as commercial purpose

C# code to get live updates from NSE:

using System;

using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;
using System.Web;
using Newtonsoft.Json.Linq; //download Newtonsoft dll from web
using Newtonsoft.Json;

namespace Check
{
    class Program
    {
        static void Main(string[] args)
        {
            //IDFCBANK

        string[] item = {"ICICIBANK","HDFCBANK"}; 

        foreach(string str in item ) 
        {
            string url = "http://finance.google.com/finance/info?client=ig&q=NSE:" + str;
            string output = "";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            try
            {
                WebResponse response = request.GetResponse();
                using (Stream responseStream = response.GetResponseStream())
                {
                    StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                    output = reader.ReadToEnd();
                    write(output);
                }
            }
            catch (WebException ex)
            {
                Console.WriteLine("Item invalid : " + str);
            }
        }

        Console.ReadKey();

    }

    static void write(string res)
    {
        try 
        {
            if (res.Length > 0)
            {
                res = res.Replace("[", "").Replace("]", "");
                JObject rss = JObject.Parse(res);

                string Title = (string)rss["t"];
                string Time = (string)rss["ltt"];
                string Charge = (string)rss["l"];
                string Change = (string)rss["c"];
                // James Newton-King
                Console.WriteLine(Title.Substring(0,3) + " " + Time + " " + Charge + "  " + Change);


            }

        }
       catch (Exception  ex)
       {
       }
        }

    }
