Here is my non fancy way to fix this.

import requests
from requests.auth import HTTPBasicAuth
def get_sentiment(self): 
        today, three_days_prior = self.get_dates()

        url = "https://data.alpaca.markets/v1beta1/news"
        params = {
            'symbols': self.symbol,
            'start': three_days_prior,
            'end': today
        }
        headers = {
            "APCA-API-KEY-ID": API_KEY,
            "APCA-API-SECRET-KEY": API_SECRET
        }

        response = requests.get(url, params=params, headers=headers)
        if response.status_code == 200:
            news_data = response.json()

            # Extracting news from the 'news' key in the response
            news_items = news_data.get('news', [])
            if news_items:
                news_headlines = [item["headline"] for item in news_items]
                probability, sentiment = estimate_sentiment(news_headlines)
                return probability, sentiment
            else:
                print("No news items found in the response")
                return None, None
        else:
            print(f"Failed to fetch news: {response.status_code}")
            return None, None

I installed the wrong package. The problem mentioned above is solved by installing the repository: https://github.com/alpacahq/alpaca-trade-api-python.git instead of just installing alpaca-trade-api.

Funny, I didn't see this issue so I ended up fixing the project up with the newer Alpaca package and added some QoL things: https://github.com/grantreighard/MLTradingBot
