How to filter the list during a RestAPI call?

I should access the list stored in another place. This list has only strings, but during an API call I should get not all of them, i.e. filter the data.

For example, here's the list:

1. Shop 1
2. Shop 2
3. Shop 3
4. Shop 4

And I want to get only 'Shop 1' and 'Shop 3'

Sample code:

api.appRest.get("o11.GetShopsList") // Should I add something here at the end?
