Hi,
Short answer: The API does not seem to directly provide such info, but
you could use action=compare, then search for class=\"diff-lineno\"
and divide by 2 (it appears once on each side of the diff).
Do note that the question you ask is not very well defined. The method
above will give you the number of chunks the diff engine displays,
which can be different from what you consider as a modification. For
instance
https://ro.wikipedia.org/w/api.php?action=compare&fromrev=9648318&t…
shows 1 chunk, but there is a modified line and an added line (the
category), which you might consider as 2 different modifications. You
need to clearly set the expectations before searching for a solution.
fwiw, Pywikibot has an APISite method "compare" to fetch the MediaWiki diff
https://doc.wikimedia.org/pywikibot/api_ref/pywikibot.html#pywikibot.site.A…
and another function "html_comparator" to convert the MediaWiki diff
into something a bit more usable for simple uses
https://doc.wikimedia.org/pywikibot/api_ref/pywikibot.html#pywikibot.diff.h…
We have one unit test that puts these two functions together in a
hopefully understandable fashion
