Call to undefined function wp_insert_link() When Using wp_schedule_event

I am working on a plugin that allows for insertion of links to the wordpress database.

When I explicitly run the plugin from inside my admin panel it runs successfully no problem. However, when running the plugin via scheduled_events it fails and I get the following error:

PHP Fatal error: Call to undefined function wp_insert_link()

The scheduled_events are running no problem when they should (hourly), so I know that action was set up successfully.

Code fails on this line:

$link_id	= wp_insert_link( $linkdata );  //insert or update our link

Want to note that the scheduled event is calling the same function that is called from my action in the admin panel.
