TicketMaster Discovery API returning few/no events when specifying "city" parameter in search

I'm trying to use TicketMaster's "Discovery API" for a hobby-project of mine, to get a list of events in my city.

The strange thing is that I receive very few hits, compared to searching for the same city on TicketMaster's own site.

As an example, here is my request:https://app.ticketmaster.com/discovery/v2/events.json?size=200&city=Oslo&apikey=XXXXXXXX

As of writing this post, I get 15 results. While doing the search on the website I get over 2000 results.

I tried adding "country=NO" (for Norway), but I get the same 15 item result.

I am using the "Ticketmaster.Discovery" nuget package, however posting the request directly in the browser has the same outcome.
