Q:

MediaWiki API: return less results from a generator than the default of 10

The following link returns information for 10 pages.
http://en.wikipedia.org/w/api.php?action=query&generator=search&gsrsearch=Skydive&format=json&gsrprop=snippet&prop=info&inprop=url&rawcontinue
How do I get this query to return information for just one page?
Setting ptlimit, cmlimit, ect ... to 1 give me the following error.
Unrecognized parameter ptlimit

The gsroffset defaults to 10.  I tried putting this parameter into the query but it just added whatever number I put to 10.  

A:

You used generator=search, so you have to check the parameters in API:Search where you discover it's called srlimit; prefix a g because you use it as generator, that gives a gsrlimit=1.
