Python FastAPI
Task:
Develop a comprehensive application (API service) that retrieves real-time price data from multiple crypto exchanges, including Binance and Kraken.
Requirements:
1. Create an API service in Python 3.x using the FastAPI framework.
2. Implement a WebSocket connection to retrieve price data.
3. The application should provide an interface to fetch data for any currency pair from the specified exchanges.
4. Include two filters or parameters: pair (nullable) and exchange (nullable).
5. If neither the pair nor the exchange is specified, display all prices from both exchanges, considering aggregation.
6. If only the exchange is specified, show all prices from that particular exchange.
7. If both the exchange and pair are specified, display prices for the specified pair.
8. The application should not rely on REST API or make real-time requests at the time of the API service call.
9. Deploy the application using Docker.
10. The application should not require a database or save any data.
Additional Details:
1. The crypto exchanges have different trading pairs, such as BTC_USDT, ETH_USDT, and more.
2. Each trading pair has a buy and sell price. Calculate the average value between these two prices for each pair.
3. The API service should provide prices for all trading pairs available on the exchanges.
4. Take into account that the pair names may vary across exchanges. Normalize the pair names to a common format.

2. А ви читайте уважніше і зрозумієте які multiple, написано ж, бінанс і кракен.
3. Нє ну тут взагалі смішно звучить, "якщо exchange не вказано, то з яких "display all prices from both exchanges," показувати? "Ви ж парсити будете з бінанс і кракен, то які both exchanges?Як ви думаєте?
4. Ні це не тому що сьогодні 1 квітня, а тому що такий проект я вже сам і виконував недавно -
"retrieves real-time price data from multiple crypto exchanges, including Binance and Kraken." - > "отримує дані про ціни в реальному часі з кількох криптобірж, включаючи Binance та Kraken."
