谷歌安全浏览API不返回威胁url

我正在向谷歌安全浏览API发送请求。我相信我正确地遵循了他们的文档。我试过重新生成我的密钥。

我正在发送下面的请求

POST https://safebrowsing.googleapis.com/v4/threatMatches:find?key=AIxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx HTTP/1.1
User-Agent: Fiddler
Host: safebrowsing.googleapis.com
Content-Length: 511
  {
    "client": {
      "clientId":      "yourcompanyname",
      "clientVersion": "1.5.2"
    },
    "threatInfo": {
      "threatTypes":      ["MALWARE", "SOCIAL_ENGINEERING"],
      "platformTypes":    ["WINDOWS"],
      "threatEntryTypes": ["URL"],
      "threatEntries": [
        {"url": "http://www.urltocheck1.org/"},
        {"url": "http://malware.testing.google.test"},
        {"url": "http://www.urltocheck2.org/"},
        {"url": "http://www.urltocheck3.com/"}
      ]
    }
  }

并得到一个空的响应，这不是我期望的与url提供和遵循他们的例子。
