Request Body Parameters

To calculate the distance between geographic points, you'll need to construct a JSON request body with the following parameters:

data: An array of geographic points, each represented by longitude and latitude coordinates. Each point should be specified as an object with "lon" (longitude) and "lat" (latitude) keys.
Example:
```
"data": [
    { "lon": "103.8321", "lat": "1.3051" },
    { "lon": "103.8597", "lat": "1.2823" },
    { "lon": "103.8469", "lat": "1.2895" },
    { "lon": "103.8448", "lat": "1.2842" }
]
```
unit: (Optional) The unit of measurement for the calculated distance. Supported values are "km" (kilometers) and "mi" (miles). Default is "km" if not specified.
Example:
```
"unit": "mi"
```
decimal_places: (Optional) The number of decimal places to round the calculated distance to. Default is 2 if not specified.
Example:
```
"decimal_places": "2"
```

Example Request

Here's an example of a complete request body:

{
    "data": [
        { "lon": "103.8321", "lat": "1.3051" },
        { "lon": "103.8597", "lat": "1.2823" },
        { "lon": "103.8469", "lat": "1.2895" },
        { "lon": "103.8448", "lat": "1.2842" }
    ],
    "unit": "mi",
    "decimal_places": "2"
}
