Get Contracts & Assets information from Cisco API using Python

Question

I would like to get Contracts & Assets information from Cisco API using Python.

I found the Service API documentation: https://developer.cisco.com/docs/service-apis/#!introduction-to-cisco-services-apis

Some python examples in https://github.com/CiscoDevNet

But I do not succeed yet...

Has someone a simple example to get contracts in python, with the authentication part managed too?

Thanks
