I have completed the first phase of the NSE javascript api. It is available for testing and copy and pasting. Actually, you dont have to do much to use this first version.
It is a simple widget that allows you to load the top ten trades, top ten gainers and losers directly into your website with jscript. You can customize the look and feel to your taste as you have 100% control over the stylesheet.

You can check out www.nseapi.com

If you are looking for the rss feed and the json version of the api, please check here - https://www.nairaland.com/nigeria/topic-816057.0.html
