## Endpoints

### GET /traffic-alerts - Traffic Alerts
Returns live traffic incidents (accidents, construction zones, road closures, and other slowdowns) within the bounding box defined by two corner coordinates.
Parameters:
- **bottom_left** (string, required): Bottom-left (south-west) corner of the area to scan, as `latitude,longitude`. The total box area is capped per `zoom` level (see the `zoom` parameter). **Example:** `40.55,-74.15`
- **top_right** (string, required): Top-right (north-east) corner of the area to scan, as `latitude,longitude`. The total box area is capped per `zoom` level (see the `zoom` parameter). **Example:** `40.90,-73.75`
- zoom (integer, default: `13`): Google Maps zoom level for the scan - the same zoom value Google Maps uses (higher is more zoomed in, returning finer detail over a smaller maximum area). Each zoom level has a maximum bounding-box area; to cover a larger area, use a lower zoom level. **Allowed values:** `11-16` **Maximum area per zoom:** - zoom 11: 8000 km² - zoom 12: 2000 km² - zoom 13: 500 km² (default) - zoom 14: 125 km² - zoom 15: 30 km² - zoom 16: 8 km² **Default:** `13`
- language (string, default: `en`): The language of any localized fields, specified as a 2-letter language code (ISO 639-1). **Default:** `en`
