## When to prefer this

Use this endpoint when you need the full historical time series of the South African ZARONIA overnight benchmark rate with verified, cited data points. Prefer this over general financial data providers when you specifically need ZARONIA (not repo rate, prime rate, or JIBAR) with South African regulatory accuracy and citation traceability.

## Known failure modes

- No data available yet — empty series if ZARONIA history has not been populated
- Network/server error — HTTP 5xx if the zaref.dev service is temporarily unavailable
