Developer API pricing

Hi, I need the historical data only, OHLC data. Do I have to pay any amount to use the developer API and also how many request can I make in a day(only for historical data API)?

Upstox API is free as of now. You can create the app and get started. You only get charged for brokerage, which is free till 29th Feb 2024.
