# Weather Service Application
## General Info:
---
* The Weather API allows users to search for the current weather report of a city by its name. The request is made to `/weather/{city}` URL with `{city}` as the path variable.
* The city parameter is validated to ensure it is not blank or a decimal value.
If it is invalid, a `400 - Http Bad Request` response is returned.
* The API gets the current weather from either the database or consumes the WeatherStack API using an API key.
* If the latest data is not older than 30 minutes, it is retrieved from the database.
* If the data is older than 30 minutes or does not exist in the database, a request is made to the WeatherStack API, and the result is cached. If there is a cached value with the city filter as the key, the response is returned from the cache directly.
* If there is too many request for api in 10 sec, a `429 Too Many Request` response is returned.
* For usages, weather Stack Api_Key should be defined in the `application.yml` file or an `.env` file .
* The API endpoint can be found on the Swagger page at` http://localhost:8080/swagger-ui/index.html`.
