# Basic Distance Matrix Fast - POST Request

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



Let’s see how to build a Distance Matrix POST method request for the same scenario from [curbside example](https://docs.nextbillion.ai/routing/distance-matrix-api/examples/approach-destinations-on-curbside)

### Request

```bash
curl --location --request POST 'https://api.nextbillion.io/distancematrix/json?key=<your_api_key>' \
--header 'Content-Type: application/json' \
--data-raw '{
"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",
    "approaches":"curb;curb;curb"
}'
```

### Response

```json

        {
