How do I make a crypto trade using bitcoin and ethereum in the kraken trading api in python?

Question

I'm coding in python and I want to make a trade from ethereum to bitcoin and bitcoin to ethereum. I'm getting confused with the code that I asked ChatGPT to answer. My code so far is:

import time
import requests
import urllib.parse
import hashlib
import hmac
import base64
from decimal import Decimal

api_key = ""
api_sec = ""
api_url = "https://api.kraken.com"
def get_kraken_signature(urlpath, data, secret):
    postdata = urllib.parse.urlencode(data)
    encoded = (str(data['nonce']) + postdata).encode()
    message = urlpath.encode() + hashlib.sha256(encoded).digest()

    mac = hmac.new(base64.b64decode(secret), message, hashlib.sha512)
    sigdigest = base64.b64encode(mac.digest())
    return sigdigest.decode()

def kraken_request(url_path, data, api_key, api_sec):
    headers = {"API-Key": api_key, "API-Sign": get_kraken_signature(url_path, data, api_sec)}
    resp = requests.post((api_url + url_path), headers=headers, data = data)
    return resp

resp = kraken_request("/0/private/Balance", {
    "nonce": str(int(1000*time.time()))
}, api_key,api_sec)
print(resp.json())

# Example: Trade Bitcoin (XBT) for Ethereum (ETH)
pair = 'XBTEUR'  # Replace with the appropriate trading pair
type = 'buy'  # 'buy' or 'sell'
volume = '0.001'  # Amount to trade
price = '50000'  # Price per unit

endpoint = '/0/private/AddOrder'
uri_path = f'{api_url}{endpoint}'

data = {
    'pair': pair,
    'type': type,
    'ordertype': 'limit',
    'price': price,
    'volume': volume,
    'expiretm': '+30',  # 30 seconds until order expires
}

headers = {
    'API-Key': api_key,
    'API-Sign': get_kraken_signature(uri_path, data, api_sec),
}

response = requests.post(uri_path, data=data, headers=headers)
print(response.json())

I'm not getting the right function in kraken. I want to make a trade from ethereum to bitcoin and bitcoin to ethereum again. Can someone show me how to do this using my code?
