I’m no expert, but I believe the only way to get a diff via the API is through
https://www.mediawiki.org/wiki/API:Compare. I haven’t worked with it to any great degree, though, so I’m afraid I can’t help beyond pointing you in that direction.

Subject: [Wikitech-l] Stream of recent changes diffs
Dear all,
we have developed a tool that is (in some cases) capable of checking if formulae in <math/>-tags in the context of a wikitext fragment are likely to be correct or not. We would like to test the tool
on the recent changes. From
we can get the stream of recent changes. However, I did not find a way to get the diff (either in HTML or Wikitext) to figure out how the content was changed. The only option I see is to request the
revision text manually additionally. This would be a few unnecessary requests since most of the changes do not change <math/>-tags. I assume that others, i.e., ORES
compute the diffs anyhow and wonder if there is an easier way to get the diffs from the recent changes stream without additional requests.
All the best
