Sure, sorry, most info is on the forum page
To call API dialog window, on PC you need to go to add market items page, then either hold the price fill button for a few seconds or open tampermonkey menu & click "set API key" option.
No idea where or how to input public api key for use on pc. Not sure if the script still works given a few other reviews say it doesn't but that could also be because there's no info where to put the api key at. Usually something would pop up on the torn page to put the api into but this script doesn't do that. There's also nothing showing in the script itself where to put the api directly into the script. Author, can you please help?
