Test URL to return 200 or 202

[fourjs-reuben]

I'm finding that the test URL http://api.nestoria.co.uk/api?country=uk&pretty=1&action=search_listings&encoding=json&listing_type=buy&page=1&place_name=newcr to take you into the Listed Locations state is now returning a 101 response code, instead of a 200 or 202 response code. Any suggestions for an alternative test to return 200 or 202
