Exchange Rate API

This project implements an API that retrieves exchange rate data from various providers and stores it in a local database. It provides two methods for retrieving exchange rate data:

1. /currency/average - Retrieves a list of exchange rates for all sources, including the average market rate.
2. /currency/average_by_date - Retrieves a list of average exchange rates for all sources for a specified period.

API Providers

This project supports the following API providers:

• MonoBank API
• Minfin API
• PrivatBank API

For each of these providers, a common interface has been implemented, with separate implementations for each provider.

Data Synchronization

The API periodically synchronizes data with the API providers using a cron job. This ensures that the local database always has the most up-to-date exchange rate data.
