Usage

REST

from kraky import KrakyApiClient

async def get_web_sockets_token():
    kraken_api_key = ""
    kraken_secret = ""
    kraky_api_client = KrakyApiClient(
        api_key=kraken_api_key, secret=kraken_secret
    )

    ws_token = await self.kraky_api_client.get_web_sockets_token()
    return ws_token

Websocket

from kraky import KrakyApiClient, KrakyWsClient

async def get_ws_token():
    kraken_api_key = ""
    kraken_secret = ""
    kraky_api_client = KrakyApiClient(
        api_key=kraken_api_key, secret=kraken_secret
    )

    ws_token = await self.kraky_api_client.get_web_sockets_token()
    return ws_token

async def public_handler(self, response):
    print(response)

async def private_handler(self, response):
    print(response)

async def main():

    interval = 30

    ws_pairs = ["XBT/USD", "ETH/USD]

    ws_token = get_token()

    kraky_public_ws_client = KrakyWsClient("production")
    kraky_private_ws_client = KrakyWsClient("production-auth")

    asyncio.create_task(
        kraky_public_ws_client.connect(
            public_handler, connection_name="public"
        )
    )

    asyncio.create_task(
        kraky_private_ws_client.connect(
            private_handler, connection_name="private"
        )
    )

    await kraky_public_ws_client.subscribe(
        {"name": "ohlc", "interval": interval},
        ws_pairs,
        connection_name="public",
    )

    await kraky_private_ws_client.subscribe(
        {
            "interval": interval,
            "token": ws_token,
            "name": "openOrders",
        },
        connection_name="private",
    )
