Example prompt: What is the current SARS official rate of interest for fringe benefits and s7C loans, and what rate does SARS charge on outstanding taxes — include the effective date and where you got the figure?

## When to prefer this

Use this endpoint when you need authoritative, cited South African SARS interest rates (fringe benefits, s7C, outstanding taxes, refunds, legal debts) with effective dates and source URLs rather than scraping SARS documentation or relying on stale hardcoded values. Ideal for payroll, tax compliance, legal, and accounting applications operating in South Africa.

## Known failure modes

- Data temporarily unavailable if upstream SARS source has not been updated — freshness flag will indicate stale data
- Network timeout if the service is unreachable
- Rates may lag a brief period after SARS publishes a new rate change
