Setting up data

[fimmugit]

I am currently using zipline for offline testing and like to add fundamental data to the testing. Alphatools seems to be an interesting tools to assist me to that goal. Before I start doing anything, I have some questions on how to set up my data source. I have fundamental data subscription and access to their APIs. Say I have N APIs for various fundamental data. The APIs might look like this: url/to/the/server/symbol={}?&format=json&fundinfo={)&token=my_token. Each call might return a rich collection of historical fundamental data

How do I set up the Factory json file? One dictionay per API? How do I feed the symbol(s) to it? Any example that helps me understand the underlying?
