⚠️ Alpha — the versioned response is under active development and
may change without notice. The default response is stable.

Returns one monitor in full: what GET /v1/monitors returns for it,
plus the query and rules that define it.

The Observe-Api-Version header picks one of two response shapes.

Default (no header). The long-standing body — id, name,
description, disabled, health, ruleKind, monitorVersion,
definition, actionRules and effectiveScheduling — which does not
change. The schema on this page describes the versioned shape, not this
one.

Versioned. Observe-Api-Version: 2026-10-06 or later returns the
Monitor-Resource below, which matches the list: the list's audit and
health fields, durations in seconds, and no definition wrapper. It is rolling out
account by account; until it
reaches yours, the header returns 403. An earlier or unparseable date
returns the default shape.

POST /v1/monitors, PATCH and DELETE take the versioned shape too.
