If you are building a JavaScript app, and if what you’re looking for is available in the larger JSON object, you can iterate through the whole response and check for matching key-value pairs. This would be done primarily client-side though, rather than with WordPress.

Alternatively, you can create a separate WordPress plugin that extends the current JSON API methods and create additional controllers that return an array of the result of your desired queries.

i didn’t try any of the suggestions for modifying the parent theme because i don’t want to modify it. i added the code that globaltimoto suggested to the child theme and that worked. thanks!
