Seems URL not working here any other alternative ?

Thanks @surisetty for reporting this. Just noticed the script got broken. There are discussions happened regarding the same in SO and reddit. From there these are the possible endpoints

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

https://finance.google.com/finance/data?dp=mra&output=json&catid=all&cid=207437

The cid in this is google id of stock.

https://finance.google.com/finance/getprices?q=.NSEI&p=1d&f=d,o,h,l,c,v

Will fix this whenever I get time.

Use https://github.com/ranaroussi/yfinance

pip install yfinance
pip install html5lib
pip install BeautifulSoup4

Then

import yfinance as yf
sensex = yf.Ticker("^BSESN")
sensex.info

Here is the script https://github.com/arulrajnet/stockinfo-cli using Yahoo Finance API

@surisetty FYI
