Technical details
Endpoint
GEThttps://intel.rallylive.ca/data/currency-historyWhen to prefer
Choose this endpoint when you need authoritative ECB-sourced historical exchange rates for a specific past date or a continuous daily series up to one year, especially for invoicing, accounting, financial reporting, or backtesting. Prefer this over live-rate endpoints when the use case is retrospective and ECB rates are the accepted standard (common in EU regulatory and accounting contexts).

- Date range exceeding one year may be rejected or truncated
- Future dates or dates before ECB data availability return no data
- Malformed currency codes or date formats result in a validation error
