by coincidence, this object is also queried, when calling the /api/ping
endpoint: see in the "meta request"
section of the result.

Maybe some system admins may have chosen to include this ping url in
their availability monitoring, in particular for their own Overpass API

There's one important thing to notice here:

The /api/ping endpoint will always report back the status of the main
Overpass API instance at, even if you're running the
/api/ping script on your own Overpass API instance (!!!).

If you're using this endpoint for system availability monitoring, be
sure to adjust BASE_URL, so it points to your own installation instead.


ps: This script is also mentioned in the OSM wiki [1], but I don't know
if it is part of the official API or if it could be simply blocked to
avoid unnecessary load from the outside world.
