Run the URL health check

Launches an asynchronous request to simultaneously run Launch a GREP request, Get domain details with dig, Request content with cURL, and Test network connectivity with MTR operations for a URL. Successful operations return fetched GREP, dig, cURL, and MTR data. For operations in progress, the returned object consists of only three members, retryAfter, requestId, and link. In this case, wait for the duration of the retryAfter interval and use the requestId to run the Get a URL health check response operation or simply GET the link.
