CLI to search all node attributes against A2 server

I want to move to the new Effortless pattern (meaning I’m thinking about what it would be like to live without my beloved chef server).

 But I cannot and will not get rid of my chef server until I’m able to search all my node attributes against A2.

I’ve been a Chef customer for years, and I have come to depend upon the “knife node search ...” capabilities.   

 I cannot lose my “knife search node...” functionality. I don’t care about searching in recipes (fortunately we never did that) but I do want to search on the command line, so I can easily inventory and answer questions about my infrastructure.

When my boss walks into my office to ask, how many Linux servers are running kernel version X, I want to answer that by asking my configuration management tool since it knows everything about all my nodes.

    Looking at the A2 API documentation here
    https://automate.chef.io/docs/api/#operation/GetAttributes

    I'm getting closer to implementing my own CLI utility to dump node objects from A2 instead of the Chef server, but I'm not quite there...this is my curl command:

    curl -k -s -H "api-token: $TOKEN"https://chef-automate2.slac.stanford.edu/api/v0/cfgmgmt/nodes/$node_id/attribute

    But the response is a string instead of a json object that I can use. Is there a working ruby program or other example of the equivalent of 'knife node show [node] -l -F json' ?

    in the mean time, could we get an example (or blog post) about how to use curl/ruby/python to get all node attributes from A2 using REST?  I heard that A2 indexes by GUID instead of node name, but I don't know how to use REST API to search all node attributes.
