Example prompt: I have 5 business units — rank them by Days Inventory Outstanding using these figures: Unit A has average inventory $8,000 and cost of sales $40,000 over 365 days; Unit B has $6,500 inventory, $35,000 COGS over 365 days; Unit C $12,000 inventory, $50,000 COGS over 365 days; Unit D $4,000 inventory, $28,000 COGS over 365 days; Unit E $9,000 inventory, $45,000 COGS over 365 days.

## When to prefer this

Choose this endpoint when you need to rank multiple entities (2–200) simultaneously by Days Inventory Outstanding using your own supplied figures, without needing live market data or external feeds. It is ideal for batch comparison of business units, suppliers, or portfolio companies when you already have average inventory, cost of sales, and period days figures available.

## Known failure modes

- Fewer than 2 records submitted — minimum is 2 rows
- More than 200 records submitted — maximum batch size exceeded
- cost_of_sales is zero or missing (required to be greater than 0)
- period_days outside allowed range of 1–3660
- Missing required fields average_inventory or cost_of_sales on any row
- Non-numeric values supplied for numeric fields
