/metrics/

The /metrics endpoint provides quick access to all of the metrics & insights
available via the Kernel API. If you already know a particular metric code for
an insight you'd like to quickly pull, the /metrics endpoint is your best path
forward.

A common workflow for the metrics endpoint would be to first use the
/metadata endpoint to retrieve a list of available metric codes. Once these
metric codes are obtained, they can subsequently be queried through the
/metrics endpoint to retrieve the actual values for these metrics.
