## Get a file

**get** `/files/{file_id}`

Retrieve metadata for a single file in your namespace.

### Path Parameters

- `file_id: string`

### Returns

- `File = object { id, created_at, mime_type, 8 more }`

  A file in the caller's namespace.

  - `id: string`

    File identifier, referenced as ImageRef.file_id.

  - `created_at: string`

    Creation timestamp.

  - `mime_type: string`

    MIME type of the stored bytes (for example, image/jpeg).

  - `purpose: FilePurpose`

    How the file is intended to be used in a generation. `input` is the primary subject (e.g. the source image for an edit); `reference` is style/content guidance.

    - `"input"`

    - `"reference"`

  - `size_bytes: number`

    Size of the stored object in bytes.

  - `state: FileState`

    Lifecycle state of an uploaded file. `pending` until bytes are received and the ingest pipeline runs; `ready` once it can be referenced from a generation; `failed` if ingest/moderation rejected it; `deleted` after a soft-delete.

    - `"pending"`

    - `"ready"`

    - `"failed"`

    - `"deleted"`

  - `deleted_at: optional string`

    Soft-delete timestamp, if the file was deleted.

  - `expires_at: optional string`

    TTL set at upload, if any. After this time Luma may automatically delete the file and reclaim its bytes — you don't need to call DELETE yourself.

  - `failure_reason: optional string`

    Human-readable reason when state is failed.

  - `filename: optional string`

    Original filename supplied at upload, if any.

  - `user_id: optional string`

    The opaque end-user tag supplied at upload, echoed back unchanged. Abuse-attribution only; not an access-control primitive.

curl https://agents.lumalabs.ai/v1/files/$FILE_ID \
