Binance Websocket API allows real-time streaming of market data, including order book depth updates, trades, and kline/candlestick chart data. It uses the Websocket protocol to maintain a persistent connection between the client and the server, and allows for efficient data transmission and real-time updates.
To use Binance Websocket API, you need to first create an API key on the Binance website and then use it to authenticate your requests. You can then subscribe to various streams of data by sending a JSON payload to the server. For example, to subscribe to real-time updates of the BTC/USDT order book, you can send the following JSON payload:
```
{
"method": "SUBSCRIBE",
"params": [
"btcusdt@depth"
],
"id": 1
}
```
The server will then stream real-time updates of the order book to your client. You can also unsubscribe from streams by sending a similar JSON payload with the "UNSUBSCRIBE" method.
Binance Websocket API is a powerful tool for building real-time trading applications and monitoring market activity. However, it requires some programming skills and knowledge of the Websocket protocol.
