Import JSON feed into Wordpress Post (wp_insert_post) every 24 hours

I am importing a JSON feed using a php file I am then looping through the JSON data and creating/updating a post using the wp_insert_post function. I want to query the JSON feed every 24 hours to sync any new information to Wordpress. I thought having something like zapier hit the page every 24 hours to run the php could work but it seemed there must be a better way to do that in wordpress/php?
