Overview

  • message_status : a simple message that gives information about the last fetch

  • http_status : status of the http response

  • feed_url : url of the feed

  • next_fetch : Time when the feed will be fetched again (this is purely informative and it might change)

  • items : array of new items detected (might be empty)
