Response fields and how to read them
The table follows the official response contract, including nested fields and useful response metadata. [] denotes an array item. Required means required within its parent object, not that a conditional parent always exists. A nullable type permits null; an optional field can be absent. Use the documented conditions below to distinguish missing, empty and zero values. Units and reporting windows apply only where explicitly documented.

Coverage, units and freshness
Rates are fractional percentages. Distinguish the raw settlement interval from normalized rates before comparing exchanges.
Inspect any returned observation time, cache status, watermark, pagination and errors using their documented meanings. A successful request alone does not establish complete coverage. Where no freshness or completeness guarantee is documented, treat it as unknown. Saved Examples are historical and viewing them does not refresh data or execute a new call.
