external API request

[DEMBLANS Mathieu]

Hi,
Anyone know if there is a way to request an external API throught a 
spamsassassin plugin ?
It will be to search an URL extracted by SA from a body of a mail and check if 
it's referenced with an API request on an external service (virustotal or 
other).
We receive some mails with URL inside whose page contains malware.
One day, a user will click on it...
If I can junk it before, it would be great.
