IEX API Websocket加密

Question

是否可以从股票部分（https://iextrading.com/developer/docs/#crypto）像IEX市场数据（https://iextrading.com/developer/docs/#deep所示）使用网络套接字获取加密货币数据，例如BTCUSDT？

我使用的代码代替fb，我将获得有关加密货币的数据：

const url = 'https://ws-api.iextrading.com/1.0/deep'
 const socket = require('socket.io-client')(url)
 socket.on('connect', () => {
    console.log('Connected');
    socket.emit('subscribe', JSON.stringify({
        symbols: ['fb'],
        channels: ['trades', 'book'],
    }))
})
socket.on('message', message => console.log(message))
socket.on('disconnect', () => console.log('Disconnected.'))
socket.on('error', () => {
    console.log('error')
})
