}

This response indicates that the KOSPI Composite is valued at 0.00085 relative to USD. Understanding these rates is crucial for converting KOSPI prices into ARS, CLP, and COP.

Historical Rates Endpoint

Accessing historical rates is vital for analyzing trends over time. The Historical Rates endpoint allows users to query exchange rates for any date since 1999. For instance:
