Like spystath menrionned, all journals have an RSS Feeds stream or more, so I use RSS Feeds with my webapplication https://www.feedsapi.org/ to receive curated alerts in realtime (many of our users have this as use-case as well).
You can also use the rss feeds with a service like IFTTT or Zapier to set up an alert system.
