How does Bse or Nse provide eod data?

#1
Hi Friends,

As there are many websites provides eod and real time data. Some charge for it and some offer for free. Since BSE and NSE is the source for all those data, how these websites get those data?

I am more curious to know how to get data from Bse and Nse directly instead of relaying other websites.

Do Nse or Bse charge for this? if so how much would be?

Any informationis on this really appriciated.

Thanks,
Nanda
