Calls with 'Demo account API Key' end with 400 Bad request

Looking into the source code I see that when an API key is provided, it automatically uses the PRO endpoint. That is always not correct. The PRO endpoint is for paid subscription tiers only. There is also a demo account API key option (which is limited but free), which still needs to use the normal endpoint. Would you mind if I fixed that? :)

Perhaps you can fork it with the changes?
