Funny thing it indeed exists. I was wondering how did i manage to break "if file exist on server" checks and just now realised he has found all the files when using JSON.
I will contact you later if i fail to found a tool for that.
There is a workaround to first get the original post id, then go to the actual page and parse HTML... But that's not worth it since most of the results i've checked are deleted permanently (takedown requests and stuff).
I wonder if we can add reason to the API?
