[SOLVED] Connecting to "Iex" or "morningstar" and retrieve data

Connecting to "Iex" or "morningstar" and retrieve data

I try to retrieve historical financial Data from iex or morningstar. For this I use the Following Code.

import pandas as pd
pd.core.common.is_list_like = pd.api.types.is_list_like
import pandas_datareader.data as web
import datetime

start = datetime.datetime(2019, 1, 1)
end = datetime.datetime(2019, 1, 10)
facebook = web.DataReader("FB", 'morningstar', start, end)

print(facebook.head())

Unfortunatly I get the error message:

NotImplementedError: data_source='morningstar' is not implemented

ValueError: The IEX Cloud API key must be provided either through the api_key variable or through the environment variable IEX_API_KEY

depending on which of both sources I use.

I tried to

pip uninstall pandas-datareader
pip install pandas-datareader

several times and also restarted the kernel but nothing changes. Was there any change to this APIs or am I doing anything wrong?

Solution

From the documentation:

You need to obtain the IEX_API_KEY from IEX and pass it to os.environ["IEX_API_KEY"]. (https://pandas-datareader.readthedocs.io/en/latest/remote_data.html#remote-data-iex) I don't know if the IEX API still works.

The morningstar is not implemented. The following data sources (at the time of writing) are:

    Tiingo
    IEX
    Alpha Vantage
    Enigma
    Quandl
    St.Louis FED (FRED)
    Kenneth French’s data library
    World Bank
    OECD
    Eurostat
    Thrift Savings Plan
    Nasdaq Trader symbol definitions
    Stooq
    MOEX
