# List an agent's versions

`GET /code/agents/{agentId}/versions`

## Request

- Base URL: `https://api.caveman.so/api/v1`
- URL: `https://api.caveman.so/api/v1/code/agents/{agentId}/versions`
- Auth: one of:
  - OAuth 2
    - Authorization code: `/api/v1/oauth/authorize`
    - Token URL: `/api/v1/oauth/token` scopes: `code:read`
  - HTTP bearer
  - API key in cookie `cave_access`
  - API key in cookie `__Secure-cave_identity.session_token`

GET /api/v1/code/agents/{agentId}/versions on the Caveman Cloud control plane. Requires the code:read scope. Not exposed to autonomous agents: The Agents API is driven by a service account's code:run key, or by a person in the Code app and console. An agent connection works inside a Code session and never starts, lists or drives Code sessions or agents from a control-plane connection.
