Usage

CLI

Kraky provides a CLI that matches the API function names and args.

You can use it like the following:

kraky get_ohlc_data pair=XBTUSD interval=240

You can replace get_ohlc_data by any kraky API function and pair=XBTUSD or interval=240 by any function argument. Please respect the format key=value.

It also supports .env files so you can also create a .env file with your api_key and secret and kraky will pick them up.

Example:

KRAKEN_API_KEY=""
KRAKEN_SECRET=""

Sync REST API

from kraky import KrakyApiClient


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

    ws_token = kraky_api_client.get_web_sockets_token()
    return ws_token

get_web_sockets_token()

Async REST API

from kraky import KrakyApiAsyncClient


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

    ws_token = await kraky_api_client.get_web_sockets_token()
    return ws_token

asyncio.run(get_web_sockets_token)

Websocket

import asyncio
from kraky import KrakyApiAsyncClient, KrakyWsClient


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

    ws_token = await kraky_api_client.get_web_sockets_token()
    return ws_token


async def public_handler(response):
    print(response)


async def private_handler(response):
    print(response)


async def main():

    interval = 30

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

    ws_token = await get_ws_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",
    )


if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.create_task(main())
    loop.run_forever()
