Python code for calling 123 API

Does the API support creating a new universe with new rules?

I’ve tried the following: client.universe_update({‘type’: ‘Stock’, ‘rules’: ‘EPSexclxorq’, ‘StartingUniverse’: ‘Easy To Trade US’}) but got the message: ‘API request failed: Cannot deserialize rules parameter value’.

EDIT: got it to work with client.universe_update({‘type’: ‘Stock’, ‘rules’: [‘EPSexclxorttm’], ‘startingUniverse’: ‘Easy To Trade US’, ‘currency’: ‘USD’})

Best,

Victor
