In this request:

start_date: The beginning date of the time series, formatted as YYYY-MM-DD.
end_date: The end date of the time series, also formatted as YYYY-MM-DD.
base: Again, this will be TWD.

Example Time-Series Response

Here’s an example of a response you might receive from the Time-Series Endpoint:

{
"success": true,
"timeseries": true,
"start_date": "2023-09-01",
"end_date": "2023-09-07",
"base": "TWD",
"rates": {
