You should find a way not to use namespace. As an industry we are moving away from TS only features.

There are many ways to go about this.

1. Keep it in the controller
2. Move the fetch to the model
3. Create a service class that you and move the fetch there
4. Use some fancy pattern to achieve the result

Which ever you choose, don't make it more complex than you need to. The logic is quite easy to refactor if and when you need to.

Be aware that your API (When you move there) probably should use a JSON Resource
