### Example

```python
import os
from plaza import Plaza

client = Plaza(
    api_key=os.environ.get("PLAZA_API_KEY"),  # This is the default and can be omitted
)
map_match_result = client.map_match.match(
    trace={
        "coordinates": [0],
        "type": "Point",
    },
)
print(map_match_result.geometry)
```
