Get metric metadata
GET/metadata
Returns metadata for Nobl9 public Prometheus API for SLO time series metrics.
Metadata is generic per-metric information such as its type, help text, and unit, and does
not depend on stored data. Pass the metric query parameter to return a single metric;
omit it to return metadata for all public metrics.

Successful metadata retrieval
Bad request — invalid or unparseable parameters (for example, a malformed PromQL
expression or timestamp), or a query that exceeds the query limits (too many series,
time range too long, or too many result points). Returned as a Prometheus-style JSON
error with errorType: bad_data.
Unauthorized — missing or invalid authentication. Triggered when the Authorization
header is absent or the access key (Client ID / Client Secret) is invalid. Returned as
a plain-text body, for example missing Authorization request header.
Internal server error — an unexpected failure while resolving metrics or executing the query. Returned as a Prometheus-style JSON error.
