# Weather

## /weather

This endpoint retrieves weather information for a specified city. It accepts a GET request with query parameters including the `city`, `format`, and `lang`. If any of these parameters are missing, it returns a custom HTML page indicating missing parameters. If the city is not found, it throws an error. If the weather data is successfully fetched, it returns the temperature, weather description, time of observation, and the city name. If the weather data retrieval fails or an error occurs, it returns a corresponding error message with a status code of 500.
