I have created a piugin named `SwagMasterAPI`. I have to get some products from different API. But when I try to add it to the service I am getting following error:

`The service "SwagMasterApi\Service\CarService" has a dependency on a non-existent service "MasterDataApi\Model\Api".`

Here are the files I have created.

carService.php

```
 use MasterApi\Model\Api; 

 class CarService {

 public function \_\_construct(Api $api) { $this-\>api = $api; } 

```

services.xml
