NotImplementedError: data_source='iex' is not implemented
I am trying to get some stock data through pandas_datareader in jupyter notebook. I was using google, but that does not work anymore, so I am using iex.
import pandas_datareader.data as web
import datetime
start = datetime.datetime(2015,1,1)
end = datetime.datetime(2017,1,1)
facebook = web.DataReader('FB','iex',start,end)
However, it comes back with the following error.
NotImplementedError: data_source='iex' is not implemented
Can anyone help me how to solve this issue please?
Answer
Many DataReader sources are deprecated, see updated list here.
Many now require API key, IEX is one of them:
Usage of all IEX readers now requires an API key.
Get API key from IEX Cloud Console, which can be stored in the IEX_API_KEY environment variable. Just execute this is separate cell in Jupyter Notebook:
os.environ["IEX_API_KEY"] = "pk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
With free IEX account you can get 500,000 free Core messages/mo.
