list.tag AND list.show?

[Mark]

Hello! I'm trying to develop a web app that goes through lists and gives recommendations for what a user should read next based on what tags they search for. On the official API page all I see is 'list.book' but I'd like to use

'list.tag' - Get the listopia lists for a given tag.
and
'list.show' - Get the books from a listopia list.

I've looked through google and the closest approximation I've found is here:

I also tried to come up with something of my own:

but all I get back is "Invalid API permissions."

I was wondering what were the extra permissions that are required and how do I get them as well as whether anyone has ever solved a similar problem or does anyone have some suggestions.

Thank you.

Ok, I just saw a similar question asked at:

Took a couple of hours googling to find it. I'm sending an email with the details of my proposed app to customer support, hopefully if a dev comes across this I can get a quicker response.
