In the "How to import Futures" algo you have the following comments 

// QuantConnect has a special deal with Quandl giving you access to Stevens Continuous Futurs (SCF) for free. 
//If you'd like to download SCF for local backtesting, you can download it through Quandl.com.

I was wondering if this meant I can download the database for FREE to my local machine?

If so could you provide me with the API KEY that I would need to use to download this data?

Thanks
