Usage

Here's a simple example of how to use this library to fetch exchange rates for USD (U.S. Dollar):

// Initialize the ExchangeRateAPI client with your API key
ExchangeRateClient := TExchangeRateAPIClient.Create('YOUR_API_KEY_HERE');

try
  // Fetch exchange rates for USD as the base currency
  ExchangeRates := ExchangeRateClient.GetExchangeRates('USD');

  // Display the exchange rates in the Memo or any UI element
  if Assigned(ExchangeRates) then
  begin
    // Parse and use the exchange rates as needed
    // For example:
    USDRate := ExchangeRates.Values['USD'].Value;
    Memo1.Lines.Add('EUR Exchange Rate: ' + USDRate);
    
    // Add more currencies and exchange rate fetching as needed

    ExchangeRates.Free;
  end
  else
    ShowMessage('Failed to fetch exchange rates.');

except
  on E: Exception do
    ShowMessage('Error: ' + E.Message);
end;

// Free the ExchangeRateAPI client when done
ExchangeRateClient.Free;

Replace 'YOUR_API_KEY_HERE' with your actual API key from ExchangeRate-API.
