# List behaviors

GET https://api.respan.ai/api/request-logs/behavior-columns/

Lists every behavior turned on for your organization, built-in and custom, with the key it's counted under. Use the keys with the other behavior endpoints. Returns an empty list instead of an error when behaviors are off.

Reference: https://respan.ai/docs/apis/behaviors/list-behaviors

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.

## Response

### 200

The behaviors.

- `columns` (list of BehaviorCatalogEntry, required) — Built-in behaviors, then custom behaviors oldest first. Turned-off behaviors are left out. Empty when behaviors are off for the organization.
- `is_span_behaviors_enabled` (boolean, required) — Whether behaviors are turned on for the organization.
- `max_selected_columns` (integer, required) — Most behaviors one spans list or summary request can ask counts for in `behavior_columns`.
- `true_probability_threshold` (double, required) — A behavior fires on a span when its latest score is at or above this value.

## Errors

### 403 Forbidden Error

Forbidden: the API key is missing, invalid or expired; the key doesn't grant `logs:read` (Read access does).

- `detail` (string, required)

### 429 Too Many Requests Error

Rate limited. This endpoint allows 60 requests per minute per organization.

- `detail` (string, required)

## Types

### BehaviorCatalogEntry

- `id` (string, required) — Column ID, `behavior__<key>`. Spans list filters accept it as a filter key.
- `key` (string, required) — Behavior key: a built-in behavior's name (for example `refusal`) or a custom behavior's `id`.
- `name` (string, required) — Display name. For a built-in behavior, its key in title case (`Instruction Miss`). For a custom behavior, its `name`, else its `description`, else its `id`.
- `polarity` (enum, required) — Whether the behavior firing is good or bad: `negative` (an Issue), `positive` (a Win) or `neutral` (Info). Display metadata only; it does not change how spans are scored.
  - Allowed values: `negative`, `positive`, `neutral`
- `type` (enum, required) — Always `boolean`.
  - Allowed values: `boolean`
- `source` (enum, required) — `builtin` or `custom`.
  - Allowed values: `builtin`, `custom`
