Using Alpha Vantage documentation I am able to fetch data of stock listed on NSE (National Stock Exchange of India) like bellow https://www.alphavantage.co/query?function=EMA&symbol=NSE:TCS&interval=weekly&time_period=10&series_type=open&apikey=demo
But I am not able to same for options
Is there any way to get data for stock/index options from alpha vantage?
Not at the moment - everything that is currently available is on the documentation page:

If you don't want to keep any of the data or use it commercially, you can generally download the options data from any online brokerage; for example tradier
If you want to keep the data from Quandl and Intrinio, both have solid packages for options data.
Yes, it used to work before, but it's not working anymore for NSE data. It works only for BSE data now.
It's better to get data from a reliable site.
