If you know already what addon does what I need: It's faster to spy that addon, yes.
But if you want to learn how to get to the thing, you should check "how does ZOs do it". And in general it's ncie to compare addon code to "how does ZOs do it", as ZOs sources could have improved/made it easier than addons that were coded years ago (not talking about your addon here, just in general!).

Hint to sinnereso:
I don't know if ZGOO provides that too, maybe it does:
If you use "merTorchbug updated" you will have the /tbug or /tb command to open the UI, and on the tab "functions" you will find all the global API (and addon, if any other addon is enabled) functions.
You can search that for "setting" (top left) and it will filter to only matching function names with setting then.
