How can the gateway status (uptime) be read

Is there an alternative to ttnctl that allows me to automate getting the gateway uptime status (which is public as shown on the screenshot), be it a HTTP GET or JSON request or an API, so I can somehow configure email notifications notifying me if a gateway is down, without waiting for multiple devices to stop sending data, which is an indication of a gateway downtime?
