Returns the payload schema of a log event type: which fields its payload carries, addressed by the dot-paths that the payload_filter and payload_fields parameters of the list endpoint accept.

type accepts a concrete event type (sign_in.completed), a trailing-* wildcard (sign_in.*), or a bare family name (sign_in, normalized to sign_in.* when no concrete type matches — the response's event_type echoes the normalized form). For wildcard lookups the fields are the intersection across every matching event type, and matched_event_types lists what the intersection was computed over; per-type metadata (description, severity, docs_group) is present only for concrete types.

The response is the same for every instance.
