# Get a metric definition

`GET /v1/metric/definitions/{idOrSlug}`

Fetch a single metric definition by its UUID or its stable `slug` (e.g. `customer_satisfaction`). Resolution is scoped to the project — a project-owned metric wins over an org-wide one, which wins over a system metric of the same `slug`.

## Path parameters

- `idOrSlug` string, required

## Response `200`

The metric definition

- object
  - `data` union, required — Metric definition data. The variant is selected by `calculationType`.
    - LlmJudgeMetricResponse
      - `id` string, uuid, required — Unique identifier for the metric definition
      - `slug` string, required — Stable metric slug (e.g. "call_reason", "customer_satisfaction")
      - `metricId` string, required — Alias of `slug` retained for backwards compatibility. Same value as `slug`.
      - `variantId` string, uuid, required — The resolved variant this response reflects (org-scoped Default if the org has customized it, otherwise the system Default). Pass this as sourceVariantId when building a derived metric off this one to pin the exact config.
      - `versionId` string, uuid, required — The variant's current version. Immutable snapshot of the config — editing the metric produces a new versionId. Use it to detect config changes.
      - `name` string, required — Name of the metric
      - `description` string, required — Description of what the metric measures
      - `type` 'COUNT' | 'NUMERIC' | 'BOOLEAN' | 'SCALE' | 'TEXT' | 'CLASSIFICATION' | 'OFFSET', required — Type of value this metric produces
      - `scope` 'GLOBAL' | 'PER_PARTICIPANT', required — Whether metric is global or per-participant
      - `supportedContexts` string[], required — Which levels this metric can produce values at
      - `unit` object — Unit information if applicable
        - `name` string, required — Name of the unit
        - `symbol` string, nullable, required — Symbol for the unit
      - `calculationType` 'LLM_JUDGE', required — Metric evaluated by an LLM against a prompt.
    - ProviderMetricResponse

      - `slug` string, required — Stable metric slug (e.g. "call_reason", "customer_satisfaction")
