# Air Quality

PM10, PM2.5, and both headline AQIs at any coordinate — through the same open models as the weather forecasts.

- Method: `GET`
- Path: `/v1/weather/air-quality`

**Parameters**

| Name | Type | | Description |
|---|---|---|---|
| `latitude` | number | required | Decimal degrees, `-90` to `90`. |
| `longitude` | number | required | Decimal degrees, `-180` to `180`. |
| `max_age` | integer (seconds) | optional | Ask for data no older than this. Clamped to the product's own floor, so it can narrow the window but never force a refresh on every call. |

```bash
curl https://api.diraz.ae/v1/weather/air-quality \
  -H "Authorization: Bearer drz_live_…"
```
