top_n
Retrieve the top or bottom N entities by any measure from APRA banking, superannuation, or insurance datasets. Returns only the ranked rows.
Instructions
Return the N rows with the largest (or smallest) value of a measure.
The single most common agent workflow: "show me the top 10 X by Y". top_n does the rank server-side and returns only the requested rows.
Examples: # Biggest 10 banks by total capital, latest quarter top_n("ADI_KEY_STATS", "total_capital", n=10, filters={"period": "2025-12-31"})
# Most members per super fund (latest)
top_n("SUPER_FUND_LEVEL", "total_member_accounts", n=10,
filters={"period": "2025-12-31"})
# 5 lowest CET1 ratios in the latest quarter
top_n("ADI_KEY_STATS", "cet1_ratio", n=5, direction="bottom",
filters={"period": "2025-12-31"})Returns:
DataResponse with at most n records, sorted by measure in the
requested direction. Other fields match get_data.
