I have this DNS dynamic service and I need to find a way to call the API to update my dynamic IP.

The URL that needs to be call is just a .php with some GET parameters.

Is there a way to do it in CMD? Or maybe Powershell? I really looking for a very lightweight way, because this will be triggered every 1 hour.

Download cURL for Windows and schedule a job that calls it, or a .cmd file which does what you need.

In powershell v2 there is no built-in cmdlet for this, but it's still fairly simple using the WebClient class:

$wc = new-object System.Net.WebClient
$wc.DownloadString('') | Out-Null  # ignore the response if just calling an API

Put that in a file with a .ps1 extension, then invoke via a schedule like this

powershell.exe -executionpolicy unrestricted -file C:\scripts\webapi.ps1

In powershell v3 (default in Win8/Server 2012, also now released for downlevel OS), there is a new built-in cmdlet Invoke-WebRequest which does bascially the same thing, but is packaged nicely and has some other bells and whistles.
