# Approach destinations on curbside

_Implement Using_: [Distance Matrix Fast API](https://docs.nextbillion.ai/routing/distance-matrix-api/synchronous)



In this example, we take a 3 x 3 matrix with 3 origins and 3 destinations which would result in a total of 9 combinations (or elements) in the response. We will also customize our request and set:

-   `mode` set to truck
-   `approaches` for each of the `destinations`. We will set it to “curb” since we want the truck to approach all destinations on the curbside.

### Request

```bash
curl --location 'https://api.nextbillion.io/distancematrix/json?origins=34.05456317,-118.31528428|33.99167000,-118.25687955|34.00792776,-118.33063151&destinations=33.96763110,-118.23215346|33.93969502,-118.26583210|33.90184293,-118.19634326&mode=truck&key=<your_api_key>&approaches=curb;curb;curb'
