A short URI, provided by a server on behalf of a third party, may be evaluated by selecting a device agent associated with the short URI and determining a destination URI corresponding to the device agent and the short URI, the destination URI identifying a payload. The server requests the payload and determines a current payload status by evaluating characteristics of the response against response characteristics that are expected based at least in part on a payload type of the payload. A payload status report is provided to the third party indicating the determined current payload status.
