Merge 2 Data API Responses Into One?

Here’s what I’d like to do…

Provide a single publicly accessible endpoint which will return data from two Things as a single JSON response. Effectively, I’d like to “merge” the JSON response from 2 data API calls into a single JSON response.

This would be straightforward to do with an outside service like Webtask, Lambda, or Firebase functions; but I’m wondering if there’s a pure Bubble approach - even if it involves a plugin, server-side or otherwise.

Anyone have any ideas?
