One entry per show. Four shapes work: an Apple Podcasts link (https://podcasts.apple.com/us/podcast/huberman-lab/id1545953110 — an episode link works too, it resolves to the show), a bare Apple ID (1545953110), an RSS feed URL (https://feeds.megaphone.fm/hubermanlab, https://lexfridman.com/feed/podcast/ — it does not have to end in .xml), or a show name (Huberman Lab), which is resolved through Apple's search and flagged as resolvedFrom: search on the row. A number shorter than five digits is read as a name, because 1619 is a podcast. To be explicit, prefix an entry: feed:, id: or name:. Duplicates are read, and billed, once.
Example:[
"https://podcasts.apple.com/us/podcast/huberman-lab/id1545953110",
"1545953110",
"https://feeds.simplecast.com/Sl5CSM3S",
