Weather Retrieval endpoint

a production ready application that exposes an API endpoint for retrieving the current temperature in a city specified by the user. The temperature should be returned in the following three formats: Celsius, Fahrenheit, and Kelvin. You should retrieve the temperature from a public weather service, e.g. OpenWeather API.
