# List a session's files

`GET /code/sessions/{sessionId}/files`

## Request

- Base URL: `https://api.caveman.so/api/v1`
- URL: `https://api.caveman.so/api/v1/code/sessions/{sessionId}/files`
- 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/sessions/{sessionId}/files on the Caveman Cloud control plane. Requires the code:read scope. Not exposed to autonomous agents: Caveman Code files are the org's inputs for sessions and the outputs sessions wrote, uploaded and read through the Agents API by a person or a service account's key. An agent in a session reads its attached files at /mnt/session/uploads and writes /mnt/session/outputs through its runtime, never through a control-plane connection.

## Response `200`

The session's files

- object
  - `files` CodeFile[], required
    - `id` string, uuid, required
    - `name` string, required: One path segment; an input mounts at /mnt/session/uploads/<name>.
    - `media_type` string, required
    - `size_bytes` integer, required
    - `sha256` string, required
    - `purpose` 'input' | 'output', required: input: uploaded for sessions to read; output: a session wrote it under /mnt/session/outputs/.
    - `session_id` string, uuid
    - `workspace_id` string, uuid
    - `path` string: An output's path under /mnt/session/outputs/.
    - `created_by_user_id` string, uuid
    - `created_by_service_account_id` string, uuid
    - `created_at` string, date-time, required

## Other responses

- `401`: A person's sign-in or a code:run key is required.
- `403`: The role, the key's scope, or an inactive service account (cave_code_service_account_inactive) refuses.
- `404`: No such session the caller sees.
- `2XX`: Successful response. Exact status depends on synchronous or durable delivery outcome.
- `4XX`: Structured failure. `error.code` is stable; `error.request_id` is echoed in the x-cave-request-id header.
- `5XX`: Structured failure. `error.code` is stable; `error.request_id` is echoed in the x-cave-request-id header.
