There are other options in addition to paging. You can make the call with count=1000 to get back 1000 jobs (essentially a bigger page). You could also make the call with the parameter job_ids to get specific jobs. I do not know the limit to the number of job_ids provided. Most of of the other endpoints in the system tend to limit ids to 20 or 50 so I would guess it is one of those, but it is not documented.
