When doing a search for “Any” data, the API explicitly states you can leave the query string blank.
However; when doing so I get a total results of 87 items for vtype “Movie”

Example query produced by Mashape’s generator;
curl --get --include 'https://unogs-unogs-v1.p.mashape.com/api.cgi?q={query}-!1900,2017-!0,5-!0,10-!0-!Movie-!Any-!Any-!gt10&t=ns&cl=78&st=adv&ob=Relevance&p=1&sa=and'

However, running this query in the generator gives thousands of results (a little over 3600 to be precise)
Running it with Python gives me 87 results, using the exact same URL.
Running the CURL command directly with the headers gives me 0
{"COUNT":"0","ITEMS":[]}

The documentation appears to be a little off.
