解析值時遇到意外的字符：<。路徑''，第0行，位置0.同時通過mashape調用鍊金術api

Question

public class keywords 
{ 
    [JsonProperty(PropertyName = "text")] 
    public string text { get; set; } 
    [JsonProperty(PropertyName = "relevance")] 
    public string relevance { get; set; } 
} 
public class JsonData 
{ 
    [JsonProperty(PropertyName = "status")] 
    public string status { get; set; } 
    [JsonProperty(PropertyName = "usage")] 
    public string usage { get; set; } 
    [JsonProperty(PropertyName = "url")] 

    public string url { get; set; } 
    [JsonProperty(PropertyName = "language")] 
    public string language { get; set; } 
    [JsonProperty ("keywords")] 
    public keywords keyword { get; set; }  
} 

上面是我用來反序列化通過調用鍊金API接收的json響應的類。

string url =  "https://alchemy.p.mashape.com/Text/TextGetRankedKeywords?outputMode=json&text=" + text; 
var response = (Unirest.get("https://alchemy.p.mashape.com/Text/TextGetRankedKeywords?outputMode=json&text=" + text) 
    .header("X-Mashape-Key", "AlZVYH30C9mshLPNM7KiE48aFfTHp1h3A31jsnmVPccxBzW5uB") 
    .header("Accept", "application/json") 
    .asJson<JsonData>() 
    .Body); 
var status = response.keyword.text; 
var score = response.keyword.relevance; 

我收到此錯誤：

An exception of type 'Newtonsoft.Json.JsonReaderException' occurred in Newtonsoft.Json.dll but was not handled in user code

Additional information: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.

我在URL犯錯誤。在「https://alchemy.p.mashape.com/text/TextGetRankedKeywords?outputMode=json&text=」 而且我被要求網址以數組實例的關鍵字JsonData類對象
