Accessing Historical Prices for HKD

To retrieve historical prices for the Hong Kong Dollar (HKD), you will primarily use the Historical Rates Endpoint. This endpoint allows you to specify a date and receive the corresponding exchange rate for HKD against other currencies, including metals.

For example, if you want to get the historical price of HKD on a specific date, you would construct your API request as follows:
