# Columns Metadata

GET https://app.termina.ai/api/v1/data/benchmark/metadata/columns

Get metadata for all benchmark metrics/columns.

Returns comprehensive information about each metric including:
- Friendly display names
- Units (percent, ratio, scalar, dollar)
- Scaling type (geometric or arithmetic)
- Performance direction (reverse = lower is better)
- Suggested cutoff values

Reference: https://docs.termina.ai/api-reference/data/benchmark/get-columns-metadata

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Servers

- `https://app.termina.ai` (Production server, default)
- `https://app.termina.dev` (Development server)
- `http://localhost:8000` (Local development server)

## Response

### 200

Successful Response

- `columns` (list of ColumnMetadata, required) — A list of column metadata.
- `name_map` (map from string to ColumnMetadata, required) — A mapping column names to their metadata for lookup convenience.

## Types

### ColumnMetadata

- `name` (string, required) — The name of the column.
- `friendly_name` (string, required) — The friendly displayable name of the column.
- `unit` (enum, required) — The unit of the category.
  - Allowed values: `string`, `percent`, `ratio`, `scalar`, `dollar`
- `scaling` (enum, required) — The scaling type of the column. Geometric indicates exponential changes are expected, while arithmetic indicates linear changes.
  - Allowed values: `geometric`, `arithmetic`
- `reverse` (boolean, required) — Whether the column is expected to be higher or lower for better performance. False means higher is better, True means lower is better.
- `cutoff` (double, optional, nullable) — The **suggested** cutoff value for the column. This is a guideline for when the absolute value of the column is considered saturated.
