curl --request GET \
  --url http://localhost:8080/metrics \
  --header 'Authorization: Bearer <token>'

Metrics in the Prometheus text format, for a Prometheus scrape. When METRICS_TOKEN is set, send it as a Bearer token. When it is not set, the route is open, except with APP_ENV=production, where it answers 401. This is not an API key route.
