Is there any api to get ISIN code for a given symbol/instrument? Holdings api is returning a mix of BSE and NSE symbols based on the highest price (for ltp). So, even though I purchased in NSE, my holdings might consist (or usually some of the holdings) BSE symbols. If I can get ISIN as part of instruments api for a given exchange, I can write code to look up for a corresponding symbol in either BSE or NSE.
