Fing Local API

I noticed this morning that Fing now has a Local API that can be used for presence. Has anyone used this yet? Is anyone willing to work with me to figure out how to use it (since I'm clueless on these things but willing to be a guinea pig)?

I think I have my presence issues pretty well licked, but I'm willing to add one more to the mix. Independent of Hubitat Fing presence has been fairly solid, though maybe a tad slow for some.
