option to do only do list of files (skip download)

[borsna]

Via option or by omitting the destination folder?

[David-Rayner-GVC]

by option (allowing omission of destination folder could be interpreted to mean dump in pwd, if you don't read teh instructions)
But also, by calling a function from within a python script, and get a json.

is already implemented?

[borsna]

not implemented. still needs to be decided how it should be implemented.
probably by having a option flag like --list-only
