The "request" is an XML-formatted string that explains to the API what
you want to do.  "request length" is the length of that string.

The "receiver" is where the results are returned to you.  The "receiver
length" is the maximum amount of data that it can return into that
variable, and the "bytes of return data" are the amount of data that
was returned by the API.

Does that answer your question?   If not, then I'm not clear on what
you mean by "Most APIs make you tell them the first amount of data to
expect"

I'm not clear on what you think is backwards...  You send the API a
request, and it sends back a response.

The hard part is that you first have to learn the "LPAR markup language"
and/or the "Disk Management Markup Language."  And then, when you try it
it complains that it can't "connect to service."  Then you read the docs,
and see that it needs access to the as-sts service -- which you quickly
find out isn't even listed in the service table.

But that doesn't appear to be the part you're having trouble with?
