For Fmp Cloud, you could refer to this thread. I had shared the endpoints that I had used for getting the daily historical data for NSE stocks. Timeframes smaller than the day (like 15 minutes, 1 hours, etc) aren’t supported for NSE stocks. From the information that I could find, FMP is a company based out of France.
Yes, Alpha Vantage also has a similar limitation of only supporting daily timeframe historical data.
I have also come across another provider called IEX Cloud for NSE/BSE stocks but that also provides EOD historical data. They have an endpoint for intraday data but that doesn’t work for Indian stocks. For IEX Cloud, these endpoints would be helpful to get started -
- https://cloud.iexapis.com/stable/ref-data/region/in/symbols?token=YOUR-API-KEY (supported Indian Stocks symbols)
- https://cloud.iexapis.com/stable/stock/EQRELIANCE-IS/chart/1m?token=YOUR-API-KEY (1 month historical data for specific stock in daily timeframe)
