2. **Register Client:** Log in → Account Settings → API tab → Register CLIENT app
3. **Create Token:** Generate access token using client credentials
4. **Use Token:** Include as QUERY parameter in all requests

#### Example Request

```
GET https://api.airqo.net/v2/measurements/grids/64b7f3257249f0029fed743/recent?token=YOUR_ACCESS_TOKEN
