Use this endpoint when you need historical daily forex rate data for a specific currency pair over a defined date range, especially when aggregate statistics like average, min, max, and change percentage are needed alongside raw daily rates. Prefer this over live rate endpoints when the use case involves backtesting, financial reporting, trend analysis, or historical comparisons.
