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.

Standard rate limiting is applicable here: Rate Limits | Upstox Developer API

Hi, is the portfolio API free as well for example if i want to fetch holdings of a user using the upstox API?
