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.

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...

I do this, but meet the invalid api call
