Problems with free api

[ReDChicagOTypewriteR]

I would like to know that I am writing projects according to documentation when using features such as ai to predict prices, but I have a problem with the first stage, as shown in the figure below

According to the error content, if I use the free api, will I not be able to do relevant operations? Is it related to the fact that I have to use the premium subscription.

you can change the download from yahoo finance.

what is the point of a demo project if you need to upgrade ....?
from their website: '....and claim your free API key to start exploring our full data portfolio!'.

I showed a code-fix in #21

Fortunately, ALPHA VANTAGE uses the IBM data to demonstrate their API. From the example for Daily Adjusted we can get the proper link and do something like

curl "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=IBM&apikey=demo" > IBM_daily_adjusted.json

This will get us about three and half month of data. Instead of using ts.get_daily_adjusted(...) in method download_data we can read the values from the file.

This is not the best solution, but it enables us to run the script and see what it does...
