Looking for "reverse" uptime monitor.
I know there are bunch of good services for monitoring a website with ping/keyword triggers. However I'm looking for service which raise the alert if their api isn't pinged for x seconds.
For example I've got a device which sends http requests to providers api and if the uptime monitoring website won't receive one within the 60 seconds then I'm getting notified. Also daily/monthly stats of downtime would be awesome.
