Both of them. Http 404 response with an html error page. Is is mashape service problem I guess but there should be more appropriate way.
How will I distinguish service response ? It is a service call, not a web page that I can show end user…

string requestUrl = string.Format(“https://wordsapiv1.p.mashape.com/words/{0}”, word);
Task<unirest_net.http.HttpResponse<WordApiResponse>> response = unirest_net.http.Unirest.get(requestUrl)
.header(“X-Mashape-Key”, “-----”)
.header(“Accept”, “application/json”)
.asJsonAsync<WordApiResponse>();

          //???
        if (response.Status == TaskStatus.Faulted || response.Result == null)
        {
            return null;

        }

An error page, or a 404?
