| Publisher API (embed buy/sell buttons) | Free |
| Data format | HTTP / JSON (REST) + WebSocket streaming |
| Historical data | Included with the subscription |

What you can build
- Place, modify and cancel orders programmatically and stream live quotes.
- Pull holdings, positions, margins and historical candles for backtesting.
- Connect no-code partner platforms such as Streak and Sensibull without writing code.
You need an active Zerodha trading account to use Kite Connect. The API handles execution and data — build and backtest your strategy logic thoroughly before going live.
