# Get app dimension breakdown

`GET /api/app/{uuid}/traffic/breakdown/{dimension}`

Top values of one dimension for one app, summed across every bucket
in range. A synthetic `__other__` entry absorbs the long tail past
the server's top-N cap (TRAFFIC_TOPN). An unrecognized dimension
returns an empty array, not an error.

## Path parameters

- `uuid` string, required
- `dimension` string, required

## Query parameters

- `from` string, date-time
- `to` string, date-time
- `limit` integer

## Response `200`

Top values of the dimension for the app

- TrafficBreakdownEntry[]
  - `value` string
  - `requests` integer
  - `bytes_out` integer

## Other responses

- `400` — Bad request - invalid parameters
- `401` — Unauthorized - missing or invalid authentication token
- `404` — Traffic analytics isn't enabled — the binary lacks the `traffic` Cargo feature, TRAFFIC_ENABLED isn't true, or the analytics database failed to open.
- `500` — Internal server error
