3. **Import the SDK**

Once you have installed the SDK, import it into your project. With the imported SDK, create an instance of the DappLookerChartsAPI and make API calls using the API key

### Example

Here's an example of how you can use the DappLooker SDK using API key and Chart UUID

```javascript
const DappLookerChartsAPI = require("dapplooker-sdk");

async function getChartData() => {
  let chartUUID = "dc9b69d8-7ca1-45d4-8ad0-a17f915f3f0"; // Replace it with chart UUID you are working with
  let apiKey = "qzusb5p3q246ip246ab6g0p8ppzb7u"; // Replace it with your API key
  let outputFormat = 'json' // This is a optional argument, valid value is `json`.
  let filterParameter = {}; // Add Parameter if required

  let response = await DappLookerChartsAPI.getChartData(chartUUID, apiKey, outputFormat);
  console.log("API Response Data: ", JSON.stringify(response));
};

getChartData();
```
