## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability break-even-ad-cost-per-order-record-ranking-ee1b1622 -d '<json body>'
```

Example prompt: I have four product scenarios: a $100 order with $40 product cost, $10 fulfilment, $5 payment fees, $5 other costs; and a $110 order with $44 product cost, $11 fulfilment, $5.50 payment fees, $5.50 other costs — can you rank all four by their break-even ad cost per order so I know which has the most advertising headroom?

## When to prefer this

Use this endpoint when you need to compare and rank multiple retail product or order scenarios by their maximum allowable advertising spend per order — not just calculate a single break-even figure. It is ideal for batch scenario analysis (2–200 rows) where relative ranking matters, such as choosing which SKU to prioritise in a paid acquisition campaign. Prefer it over single-record calculation endpoints when comparative ordering across scenarios is the goal.

## Known failure modes

- Fewer than 2 rows submitted — minimum array length not met
- Negative or non-numeric cost values — schema validation failure
- Revenue lower than combined costs resulting in negative break-even ad cost — valid but zero-or-negative ranking result
- More than 200 rows submitted — maxItems constraint exceeded
- Missing required fields (order_revenue, product_cost, fulfilment_cost, payment_fees, other_variable_costs) — 400 validation error
