Providing FetchHttpClient.layer in WeatherApiLive or in the calling effect?

//services/weatherApi.ts

export const WeatherApiLive = Layer.effect(
  WeatherService,
  Effect.gen(function* () {
    return {
      getWeather: (city: string) =>
        pipe(
          getCityCoords(city),
          Effect.flatMap(({ lat, lon }) =>
            pipe(fetchWeatherData(city, lat, lon)),
          ),
          Effect.provide(FetchHttpClient.layer),
        ),
    };
  }),
);

//index.ts

const program = Effect.gen(function* () {
  const weatherApi = yield* WeatherService;
  const updateStream = Stream.repeat(
    weatherApi.getWeather("Calgary"),
    Schedule.fixed("2 seconds"),
  );

  yield* Stream.runForEach(updateStream, (weather) =>
    Console.log(
      `Weather update: ${weather.city} - ${weather.temperature}, ${weather.condition}`,
    ),
  );
});

const main = pipe(
  program,
  Effect.provide(WeatherApiLive),
  Effect.provide(NodeHttpClient.layer),
  Effect.catchAllCause(Effect.logError),
);

Effect.runPromise(main).catch(console.error);
