# List Agent Versions

> List an agent's saved versions, newest first.

### Overview

Returns version metadata for the agent's dev timeline, or for one branch's own saves when `branch` is set, ordered by `created_at` descending. Snapshots are omitted because they can be large; read one with [Get Latest Agent Version](/api-v2/get/agents-id-versions-latest) or, for a published version, [Get Agent Version](/api-v2/get/agents-id-versions-semver).

### Headers

<ParamField header="authorization" type="string" required>
  Your API key for authentication.
</ParamField>

### Path Parameters

<ParamField path="agent_id" type="string" required>
  The agent's unique identifier.
</ParamField>

### Query Parameters

<ParamField query="limit" type="integer" default="50">
  Maximum number of versions to return. Minimum `1`, maximum `200`. Values outside that range are clamped; a non-numeric value falls back to the default.
</ParamField>

<ParamField query="branch" type="string">
  A branch ID. When set, only that branch's own saves are listed (its base version is not included). When omitted, only dev-timeline versions are listed and branch saves are excluded. An unknown branch ID returns an empty array.
</ParamField>
