pass in a page of 1 in params and if the length or count of agents is 20, then run the same query with page+1. You are only wasting an API call if the total count is 20, because running the query over page 2 would produce no results. This is kinda how I am handling it for the home_search, but that returns a count so I can compare the returned value instead of having to iterate over the result set.
