REST API health check

Question

I have number of APIs which is not being hosted by me, so I have no control of the API itself. What I'm trying to achieve is to check whether the APIs is online or not.I already tried several way:

1. Sent a HTTP request to the API endpoint with HEAD method

2. Sent a blank HttpWebRequest

   HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
   using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
   {
       if (response.StatusCode == HttpStatusCode.NotFound)
           return false;
   
       return true;
   }
   

3. Ping the server

But somehow my end result is not accurate enough. It shows offline but when I manually try to invoke the API, it seems okay. Anybody got a solution?
