## Code samples

### cURL

```bash
curl --request GET \
  --url https://res.aireon.ch/res_api/gwr/geojson \
  --header 'token: <token>'
```

### TypeScript

```typescript
const url = 'https://res.aireon.ch/res_api/gwr/geojson';
const options = {method: 'GET', headers: {token: '<token>'}};

fetch(url, options)
  .then(res => res.json())
  .then(json => console.log(json))
  .catch(err => console.error(err));
```

### Python

```python
import requests

url = "https://res.aireon.ch/res_api/gwr/geojson"

headers = {"token": "<token>"}

response = requests.get(url, headers=headers)

print(response.text)
```
