Machine Metrics

Retrieve machine monitoring metrics for the authenticated user. Returns system, validator client, and beacon node metrics that were previously pushed via the --monitoring-endpoint flag and set up via https://beaconcha.in/user/settings#app.

Users can only access metrics belonging to their own API key. Optionally filter by one or more machine names.

Provide a time range via unix timestamps to query a specific historical window (maximum 31 days, limited by data retention). Each array is ordered newest first, then paginated toward older data.

Pagination uses an opaque continuation token that tracks the last emitted (timestamp, machine) tuple separately for system_metrics, validator_metrics, and node_metrics. Clients must treat paging.next_cursor as opaque.
