# Check for a media delta download

`GET /v1/media/{id}/delta`

## Request

- Base URL: `https://api.brixsignage.com`
- URL: `https://api.brixsignage.com/v1/media/{id}/delta`
- Auth: HTTP bearer

Used by playback devices to check whether their cached copy of a file is current. The caller sends the checksum of its cached copy and receives either the data needed to update it, or a flag indicating no partial update is available along with a URL to download the full file.

**Notes.**
- Reserved: delta downloads are not offered yet, so this always answers `deltaAvailable: false`.

## Path parameters

- `id` string, required

## Response `200`

Success.

- object
  - `data` object, required
    - `deltaAvailable` false, required
    - `downloadUrl` unknown, required

## Other responses

- `401`: Missing, expired or revoked bearer token.
- `403`: The token lacks the permission this operation needs (see `x-brix-permission`).
- `5XX`: Server error. The body carries a `requestId` to quote to support.
