I would call them “agents” at a class layer and encapsulate the logic specific to each domain in its own class. Completely arbitrary but in my mind: adapters - call other web services
dao - database calls
agent - responsible for stitching the pieces all together and doing the actual business logic.
Example: OpenWeatherAdapter - call the OpenWeather API. No business logic. H2SelectDao - get user preferences from an internal database. No business logic.
WeatherAgent(openWeatherAdapter, h2SelectDao) - All the business logic.
Note: this is in context of a API service like a middleware.
