`POST /v1/nearest/batch`

## Request

- Base URL: `https://api.terranode.co`
- URL: `https://api.terranode.co/v1/nearest/batch`
- Auth: API key in header `x-api-key`

Find nearest features for multiple points against a single dataset. Points can be provided in the request body or referenced from an existing point dataset via the points_* parameters.

## Query parameters

- `system_dataset` string
- `dataset` string
- `dataset_id` string, uuid
- `version` integer
- `n` integer
- `radius` number
- `format` 'json' | 'csv'
- `async` 'true'
- `webhook_url` string, uri
- `points_system_dataset` string
- `points_dataset` string
- `points_dataset_id` string, uuid

## Request body

- BatchInputPoint[]: Array of point objects. Also accepts a GeoJSON FeatureCollection with Point geometries (coordinates are extracted automatically).
  - `lat` number, required
  - `lng` number, required

## Response `200`

Synchronous batch result.

- BatchNearestResponse
  - `summary` BatchNearestSummary, required
    - `total` integer, required
    - `matched` integer, required
    - `unmatched` integer, required
  - `dataset` string, required
  - `version` integer, required
  - `results` BatchNearestResult[], required
    - `index` integer, required: Zero-based index of the input point.
    - `input` object, required
    - `match` boolean, required
    - `match_count` integer, required: Number of dataset features matching this point.
    - `matches` NearestFeature[], required
      - `properties` FeatureProperties, required: Key-value properties from the matched feature. Keys and values depend on the dataset.
      - `within` boolean, required: True if the query point is inside this polygon.
      - `distance_m` number, required: Geodesic distance to nearest edge in meters.
      - `distance_mi` number, required: Geodesic distance to nearest edge in miles.
  - `latency_ms` number, required
