Extract/Grab data from checkmk host

I used to grab information (e.g CPU load, CPU Utilization, Memory) from the hosts through requests.Get using python. In v1.6 there was pnp4nagios which is not available now. I also looked at the current v2’s extensive API documentation, but would anyone help direct me to which documentation to focus on or some snippets of API code to get started for my use-case? Will be very much appreciated.

Thanks!
