Quick Start

import asyncio

from pycryptoex import KuCoin, Bybit


async def handler(json_data):
    print(json_data)


async def main():
    # Request to public endpoints
    kucoin = KuCoin()
    async with kucoin:
        await kucoin.request(...)

    # Request to private endpoints
    bybit = Bybit(
        api_key="YOUR_API_KEY",
        secret="YOUR_API_SECRET"
    )
    async with bybit:
        await bybit.request(..., signed=True)

    # Start the public websocket
    kucoin_public_ws = await kucoin.create_websocket_stream()
    await kucoin_public_ws.start()
    # Subscribe handler to a public channel
    topic = "/market/candles:BTC-USDT_1min"
    await kucoin_public_ws.subscribe_callback(topic, handler)
    # Unsubscribe handler from a public channel
    await kucoin_public_ws.unsubscribe_callback(topic, handler)
    # Unsubscribe all handlers from a public channel
    await kucoin_public_ws.unsubscribe(topic)
    # Stop the public websocket
    await kucoin_public_ws.close()

    # Start the private websocket
    kucoin_private_ws = await kucoin.create_websocket_stream(private=True)
    await kucoin_private_ws.start()
    # Subscribe to private channels
    await kucoin_private_ws.subscribe_callback("/account/balance", handler)

    # Block until websockets close
    while not kucoin_public_ws.closed or not kucoin_private_ws.closed:
        await asyncio.sleep(0.1)
