# Call library.get

`POST /api/v1/tools/library.get`

## Request

- Base URL: `https://app.goosybear.ai`
- URL: `https://app.goosybear.ai/api/v1/tools/library.get`
- Auth: HTTP bearer

Read one library item by the `kind` and `id` library.search returned — 'open that video', 'where was this image made?'. Use it to confirm an item still exists and to see where it was made before you reference it; it reads only. Not for finding items by what they are — that is `library.search`.

Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with `workspace_ambiguous` and lists the choices — offer them, never pick one.

## Headers

- `x-request-id` string

## Request body

- object
  - `kind` 'image_generation' | 'storage_object' | 'video_unit' | 'document', required: The item's kind, exactly as library.search reported it.
  - `id` string, required: The item's id from library.search.
  - `workspace` string: Which workspace to run in — its slug. Omit to use your default. With more than one reachable workspace and no default, the call is refused and the choices are listed.

## Response `200`

The call was admitted and dispatched. `ok` says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.

- union
  - object: The tool ran and answered.
    - `ok` true, required
    - `kind` 'image_generation' | 'storage_object' | 'video_unit' | 'document', required: What sort of object this is — pass it back to library.get.
    - `id` string, required: The object's own id. With `kind`, this addresses it exactly.
    - `roll` 'images' | 'clips' | 'videos' | 'documents', required: Which shelf of the library it sits on.
    - `title` string, required: What it is called: the name someone typed when pinning it, else the object's own label.
    - `pinned` boolean, required: Has someone pinned this to the shelf?
    - `pinned_name` string, nullable, required
    - `finalized_at` string, nullable, required: When it was promoted into the library.
    - `source_board_id` string, nullable, required: The board it was made on, when that board still exists.
    - `source_board_name` string, nullable, required
    - `preview_image_generation_id` string, nullable, required: The image whose bytes preview it, when it has one.
    - `preview_has_bytes` boolean, required
    - `workspace` string, required: The slug of the workspace this call ran in.
    - `working_in` object, required: Which workspace this call ran in, and how that was decided. Present on every workspace-scoped result.
      - `label` string, required: The chip words — e.g. "working in: Acme Main".
      - `note` string, required: Why this workspace — e.g. "your default", "this call only".
      - `workspace` string, required: The resolved workspace's slug.
      - `source` 'call-override' | 'key-pin' | 'stored-default' | 'sole-reachable', required: Which rung of the R7 precedence resolved the workspace.
  - ToolRefusal: A call that was admitted and dispatched, and did not succeed.
    - `ok` false, required
    - `code` string, required: The typed reason — e.g. `workspace_ambiguous`, `invalid_arguments`, or the tool's own failure code.
    - `message` string, required: A sentence a person can act on.
    - `workspaces` string[]: On a workspace refusal: the slugs this key may pass as `workspace`.
    - `issues` object[]: On `invalid_arguments`: which fields failed, and why.
      - `path` string, required
      - `message` string, required
    - `path` string: On an authoring refusal: where in your call's input it points, e.g. `steps.<key>.params.<field>`.
    - `fix` string: On an authoring refusal: the change to your call that would pass.
    - `instruction` string: On an authoring refusal: what to do next with it.

## Other responses

- `400`: The request could not be used: the body is present but not a JSON object (`tenant_api.malformed_body`); it is a top-level array carrying more messages than this endpoint accepts (`tenant_mcp.batch_too_large`); or the `Idempotency-Key` header is malformed (`tenant_api.idempotency_key_invalid`), disagrees with the body's `idempotency_key` (`tenant_api.idempotency_key_conflict`), or was sent to an action that cannot replay a retry (`tenant_api.idempotency_unsupported`). Nothing ran.
- `401`: No bearer credential, or one that did not resolve. Deliberately ONE undifferentiated answer for absent / unknown / revoked / expired, so the endpoint is never an oracle over the key space.
- `403`: The credential is good but the surface is not open to it — the platform or account API switch is off, or the holder lacks the `api.access` capability. The `code` says which.
- `404`: No such tool. The body names no tool and is identical for every unrecognised name.
- `429`: Over this key's per-minute cap. Carries `Retry-After` and `error.retry_after_seconds`.
