# Get Log Column Catalog

`GET /api/v1/custom-metrics/log-columns`

Metadata-driven column catalog for the logs table (Metric Visibility panel).

Returns structural + standard columns (static registry, channel-filtered) and the
tenant's active custom metrics (from DB) as toggleable columns. Values for standard
columns are already on the log row; the frontend renders them via ``render``.

``channel`` is a ``Literal`` so FastAPI validates it (422 on anything else) and the
allowed values surface in the OpenAPI schema.

## Query parameters

- `channel` 'voice' | 'text' | 'email'

## Response `200`
