🚀 CryptoQuotes API 🌐

The CryptoQuote API provides users with real-time cryptocurrency quotes and conversion rates. It supports fetching exchange rates for multiple cryptocurrencies and their respective values. You can query this API by providing a cryptocurrency code (like BTC) and receive the latest exchange rate information from two sources: CoinMarketCap and ExchangeRates API. It is built with modern development practices and follows Clean Architecture to ensure scalability, maintainability, and separation of concerns.
