@robertlynch3 try
https://netbox.local/plugins/netbox_healthcheck_plugin/healthcheck/?format=json

@sergey-kalikin-adjust that endpoint is behind Netbox's password, so you can't use the API token to get it.

I had the same request, but then I realized I can allow that endpoint by setting LOGIN_REQUIRED = False in configuration.py. For me this is safe because I run behind a secure reverse proxy.
