Got it. Played around a lot more until I made better sense of things, then found this:
Finally found a command that can load whatever you want into the pointer:
BIG thanks to @rboss. I reattempted @anon40688970’s trick of a dummy parameter and got the whole thing working. I’ll post in the original TMDB thread with my version and any other findings in a day or so, working on stuff like a .settings file for storing the API key, language and tag mappings (prefer using %album% rather than %tvshow%).
I’d still vouch for a simpler way to point at things other than a website’s response; even though the point of a web source IS to look explicitly for new values, there’s sometimes only so much you can do with that given dataset.
Maybe a new command like PointAt that supports ID3 %placeholders% or output buffers from previous parser blocks to use as parameters or even save as tags at any part of the process…
Or a second prompt like [SearchAlbumBy] to let the user manually state more values after the first search phase to expand upon/combine results from the chosen results URL (seasons, episodes) or even during the search phase to carry values past it and straight into [AlbumURL].
Also bigger thanks to @RobertM for getting the ball rolling
