 Note that in order to be consistent with the OpenAI API naming, the service function names match exactly the API endpoint titles/descriptions with camelcase.
 Also, we aimed the lib to be self-contained with the fewest dependencies possible therefore we ended up using only two libs `play-ahc-ws-standalone` and `play-ws-standalone-json` (at the top level). Additionally, if dependency injection is required we use `scala-guice` lib as well.
