I have gone through your circular regarding changes of Kite Connect API. Here is the exact verbatim
NSE just published their circular laying out the operational specifications for retail algo trading. You can check out our overview of the circular on Z-Connect.
With this new regulatory clarity, our regulatory risk in offering the product is greatly reduced. So, we're lowering Kite Connect's price to ₹500 per month for the data (real-time + historical) APIs. The order placement and account management APIs (view holdings, positions, etc.) have been free since March 2025. The 500 rupee fee ensures that only users with serious intent sign up to use the APIs since streaming data comes with a significant bandwidth cost for us.
Now Can we take one API for Order placement , Getting quote and one for Historical API. and can we take 3-4 more purely for order placement (Market, LIMIT, GTT, GTT and OCO) and getting portfolio holdings.
You can use a single API key for both order placement and fetching market data (real-time and historical) under the ₹500/month plan. However, if you create multiple API keys on the same developer account for different use cases, you will be charged separately for each app. You can refer to the similar discussion here.
