`$client->elevation->lookupPost(?string format, ?float lat, ?float lng, ?string locations, ?string outputFields, ?string outputInclude, ?int outputPrecision): ElevationLookupResult`

**post** `/api/v1/elevation`

Look up elevation at one or more points

### Parameters

- `format?:optional string`

  Response format: json (default), geojson, csv, ndjson

- `lat?:optional float`

  Latitude (single point)

- `lng?:optional float`

  Longitude (single point)

- `locations?:optional string`

  Pipe-separated lng,lat pairs (batch)

- `outputFields?:optional string`

  Comma-separated property fields to include

- `outputInclude?:optional string`

  Extra computed fields: bbox, center

- `outputPrecision?:optional int`

  Coordinate decimal precision (1-15, default 7)

### Returns

- `ElevationLookupResult`

  - `GeoJsonGeometry geometry`

    GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

  - `Properties properties`

  - `Type type`

### Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

$client = new Client(apiKey: 'My API Key', environment: 'local');

$elevationLookupResult = $client->elevation->lookupPost(
  format: 'format',
  lat: 0,
  lng: 0,
  locations: 'locations',
  outputFields: 'output[fields]',
  outputInclude: 'output[include]',
  outputPrecision: 0,
);

var_dump($elevationLookupResult);
```
