You should be able to do this through FQL. To check if a user likes some URL:

SELECT user_id FROM like WHERE object_id in (SELECT id from object_url WHERE url="<PAGE_URL>") and user_id=<USER_ID>;

If query is empty then a user doesn't like this url. Otherwise 1 record is returned.

See like, object_url.
