Get a file

GET/files/{file_id}

Retrieve metadata for a single file in your namespace.

Path Parameters
file_id: string
format: uuid
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.

format: uuid
created_at: string

Creation timestamp.

format: date-time
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.

One of the following:
"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.

One of the following:
"pending"
"ready"
"failed"
"deleted"
deleted_at: optional string

Soft-delete timestamp, if the file was deleted.

format: date-time
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.

format: date-time
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.
