All three dimensions offer public JSON APIs and CSV downloads without an API key. Country and Currency are versioned reference snapshots; Date is generated on demand. Each explorer includes examples and field definitions.
Use common keys to join your data while retaining its original values. Geography does not automatically aggregate data, date generation does not resample observations, and currency reference data does not include exchange rates.
