Machine endpoint for the Bluetooth scale listener. Authenticated with the ingest bearer token and attributed to a configured owner rather than the Access identity.

`POST /api/ingest/weight`

**Request body** (`application/json`, required)

The scale reading to ingest.

- `weightKg` (number, required) — Scale-reported body weight in kilograms.
- `bodyFatPct` (number | null) — Optional scale-reported body-fat percentage.
- `userEmail` (string<email>) — Owner to attribute the reading to; falls back to the configured ingest user.
- `raw` (object) — Opaque raw payload from the scale, stored for debugging.

Request body example:

```json
{
  "weightKg": 72.6,
  "bodyFatPct": 17.4,
  "userEmail": "nick@mintlify.com",
  "raw": {
    "device": "withings-body+",
    "battery": 82
  }
}
```
