HttpClient.GetStringAsync returns a Task<string>.

You don't wait for it to complete, instead you call .ToString() on it, which is likely to either:

Return the full name of the Task<T> type
Return some internal string representation of the Task<T> type (unlikely)

As such, what you have is not the Json document, but the task string, which you then try to deserialize Json from.

Try:

string page = await http.GetStringAsync(searchUrl);

or:

string page = http.GetString(searchUrl).Result;
