read URL yahoo finance

[KenziTrader]

I try to read an options chain from yahoo finance with pandas_datareader. Reading the URL fails with b'Forbidden'. I can open the URL in Safari.

Do I need to do something special to give Carnets permission to open an URL?

Thanks,
Rene

Carnets and Pandas can open URLs, so I think your problem is specific to Yahoo Finance.

Looking at open issues in pandas_datareader, I see this one, which is very similar: pydata/pandas-datareader#923
There is even a suggested fix:

FB = web.YahooOptions('FB')
FB.headers = {'User-Agent': 'Firefox'}
print(FB.expiry_dates)

Yes, thanks, setting the user agent works.
