Yet another 403 error...please help a newbie

Here is the faulty code

from credentials import AlpacaConfig
import alpaca_trade_api as tradeapi

alpaca = tradeapi.REST(key_id=AlpacaConfig.API_KEY,secret_key=AlpacaConfig.API_SECRET,base_url=AlpacaConfig.ENDPOINT, api_version=‘v2’)

Fetch Account

account = alpaca.get_account()

and then
HTTPError: 403 Client Error: Forbidden for url: https://broker-api.sandbox.alpaca.markets/v2/account

Solved,
I created an account on broker-app by ignorance. I ask for a deletion and created a new one on
https://app.alpaca.markets/.
It works directly.
Thanks
