I have an abstraction of usage of repository pattern and I'm not able to do a retrofit call.

I'll go from Retrofit service to my use case.

I've AuthenticationRetrofitService

interface AuthenticationRetrofitService {

    @GET(LOGIN_PATH)
    suspend fun doLogin(@Header("Authorization") basicAuth: String) : Either<Throwable, Monitor>

    @GET(LOGOUT_PATH)
    suspend fun doLogout() : Either<Throwable,Unit>

    companion object {
        private const val LOGIN_PATH = "login/"
        private const val LOGOUT_PATH = "logout/"
    }
}

Then I have AuthenticationRetrofitApi which implements AuthenticationApi

class AuthenticationRetrofitApi(private val service: AuthenticationRetrofitService) : AuthenticationApi {

    override suspend fun doLogin(basicAuth: String) = service.doLogin(basicAuth)

    override suspend fun doLogout() = service.doLogout()

}

Then this is the AuthenticationApi

interface AuthenticationApi {

    suspend fun doLogin(basicAuth: String) : Either<Throwable, Monitor>
    suspend fun doLogout() : Either<Throwable, Unit>
}

Then I have the AuthenticationRepository

interface AuthenticationRepository {

    suspend fun doLogin(basicAuth: String): Either<Throwable, Monitor>
    suspend fun doLogout(): Either<Throwable, Unit>
}

And the AuthenticationRepositoryImpl

class AuthenticationRepositoryImpl (private val api: AuthenticationApi) : AuthenticationRepository {
    override suspend fun doLogin(basicAuth: String) =
        api.doLogin(basicAuth = basicAuth)
            .fold({
                Either.Left(Throwable())
            },
                {
                    Either.Right(it)
                }
            )

    override suspend fun doLogout() = api.doLogout().fold({Either.Left(Throwable())},{Either.Right(Unit)})

}

And from my usecase I call the AuthenticationRepository my problem is, I do not know how to link them because if I run the app I get this error.

java.lang.IllegalArgumentException: HTTP method annotation is required (e.g., @GET, @POST, etc.).

Then I'm using Kodein for dependency injection but I do not know what to bind or what to provide perhaps is that the error? Because :

AuthenticationRetrofitApi is not used AuthenticationRepositoryImpl is not used

What I'm missing?

EDIT

This is how I use Kodein for my retrofit module

val retrofitModule = Kodein.Module("retrofitModule") {

    bind<OkHttpClient>() with singleton {
        OkHttpClient().newBuilder().build()
    }
    bind<Retrofit>() with singleton {
        Retrofit.Builder()
            .baseUrl("https://127.0.0.1/api/")
            .client(instance())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
    }

//I'm not sure if I have to bind this
   bind<AuthenticationRepository>() with singleton {
        instance<Retrofit>().create(AuthenticationRepository::class.java)
    }
}
