I know that this comment isn't very helpful, but... that's HTML, not HTTP.
It's not part of the HTTP standard in any way.  If it were HTTP, it would
look like "%3c"

I would assume that the web service is doing it this way so that it will
display the text in a web browser rather than try to interpret it, but,
IMHO that's incorrect behavior.  It should, instead, return a different
content-type than TEXT/HTML.

It's your program (or perhaps Alex's?) that is putting the data into an
RPG variable, not HTTPAPI.   HTTPAPI has two ways of returning data -- it
can return it as a stream file (which is even less limited than a user
space) or it can return it by doing a callback to an RPG subprocedure in a
loop.

My guess is that Alex's code (possibly based on an earlier example that I
wrote) is saving the data that it gets from the callback into a buffer.
You could just as easily make that same routine write it to a user space,
or even to teraspace (which can go much larger than a user space)

HTTPAPI should be able to return as much as 4gb in a single transfer, I
haven't had any problems with that limit yet.
