If you want to do straight-forward API scripting, Shortcuts + Actions might do the trick.
Patterns in play:
- Fetch URL (Shortcuts built-in)
- Parse document as feed/JSON/XML
- (not sure if this is built into Shortcuts or you need Actions to cover all three)
- Pull out “the stuff” element/attribute (e.g.
items
,articles
,results
, etc.) (Shortcuts built-in) - Do something on each item.
- YMMV depending on support in whatever app you’re integrating with.
