How do I authenticate my Python session?
To make more than 50 calls in a day, or to access a premium database, you will need to authenticate your Python session by telling us your API key. To do so, simply include the key in your first function call. For example:
import quandl quandl.ApiConfig.api_key = 'YOURAPIKEY'
You should include the quotes around the API key.
Your API key will then be stored in your working directory for continued use.
