# List watermark assets

`GET /watermarks`

## Response `200`

OK

- ApidocsWatermarkAssetList
  - `data` DomainWatermarkAsset[]
    - `content_type` string — ContentType is the MIME type sniffed via http.DetectContentType from the first 512 bytes. Used as the Content-Type response header on /raw.
    - `filename` string — Filename is the on-disk basename, ALSO the stable identifier used by Stream.Watermark.Filename and every REST URL.
    - `size_bytes` integer — SizeBytes is the on-disk size of the image (from os.Stat).
    - `uploaded_at` string — UploadedAt is the file's modification time in UTC. Save sets it to the wall clock at upload; subsequent rebuilds derive it from mtime so the list survives restart without an external metadata store.
  - `dir` string
  - `total` integer

## Other responses

- `500` — Internal Server Error
