Loop through API data

Hi everyone, please excuse me while I try to adapt to the visual way…

I want to try and loop through some API data to see if I can find a value. Now in code I would find this realtaivly easy but I cant seem to figure out how to do it the wappler way.
So what I want to do is
Setup a Count Var
Get API data
Loop through data looking for the value increatement count vat by 1 for each item
Once I have found the value return true and exit out of the loop

How would I accomplish this in Wappler? Would this be a server side or a client side (or could it be either)?

Thanks for your help.
