Tiingo Data Reader

Question

I was developing a price prediction model that requires Tiingo but there seems to be problem in the API authentification. I used the OS access the Tiingo API.

`

api_key =os.environ.get('TIINGO_API_KEY')
    df=pdr.get_data_tiingo('AAPL',api_key)
    df=pd.read_csv('AAPL.csv')
    print(df.tail())

The error I got looks like:

    ~\AppData\Local\Temp/ipykernel_9920/1017009006.py in <module>
      1 api_key =os.environ.get('TIINGO_API_KEY')
----> 2 df=pdr.get_data_tiingo('AAPL',api_key)
      3 df=pd.read_csv('AAPL.csv')
      4 print(df.tail())

        182         if not api_key or not isinstance(api_key, str):
    --> 183             raise ValueError(

        185                 "through the api_key variable or through the "
    
    ValueError: The tiingo API key must be provided either through the api_key variable or through the environmental variable TIINGO_API_KEY.

Any assistance is highly appreciated

Answer 1

It seems api_key is coming as None. You should check that.
