var request = HttpUtil.get("https://boi.org.il/PublicApi/GetExchangeRates");
// Parse the response body as JSON
var jsonContent = JsonUtil.parse(request.asString().getBody());
// Convert the exchange rates to a JSON string
var exchanges = JsonUtil.stringify(jsonContent.exchangeRates);
// Create a temporary file and write the exchange rates JSON to it
var tempFile = FileUtil.createTempFile("tmp.json", exchanges);
// Return the path to the created temporary file
return tempFile;
