# Get external metadata for a label

`GET /labels/{label_id}/fetch-metadata`

Return External plugin metadata searching by object id and type

## Path parameters

- `label_id` string, required

## Response `200`

External metadata array

- union — Returns the plugin payloads when at least one metadata plugin answered, and the empty list envelope for the requested type when none did.
  - ExternalMetadataObject — `plugin` is keyed by metadata-retriever plugin name; each value is that plugin's payload.
    - `object_id` string, required
    - `object_type` string, required — The kind of object referenced, as a bare string. The set is intentionally open so a new media type is not a breaking change; values seen today include `song`, `album`, `artist`, `playlist`, `podcast`, `podcast_episode` and `video`.
    - `plugin` PluginMap, required
  - EmptyListResponse — The standard empty envelope, with an empty list keyed by the requested type.
    - `total_count` integer, required
    - `md5` string, required
