FYERS

FYERS (fyers.in) have an API Bridge with TV, so that allows to trade.
They offer equities ,futures on equities/Options, Commodity F/O, Currency F/O (In India, they have a tough limit on Currency pairs;EURUSD, EURJPY, EURGBP, USDJPY, GBPUSD and their combinations with the INR such as EURINR etc).

No Bonds sadly or cryptos (it's just been made legal,so the brokers still need to wrap their framework and get ready for it).

FYERS offer the API Bridge with TV, their own partially integrated TV platform called FYERSWEb , a desktop program called FYERSOne which looks fine and a mobile app.

UpstOx

UpstOX is good,but do not have a paper trading option.
They used to have an API bridge with TV,but have suspended it for the moment.

Interactive Brokers

Looked up IBKR (Interactive Brokers).They're very good,but their minimum requirement are often high for Indian people.
Besides,they offered a paper trading option with delayed prices
