## 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 buy-x-get-y-free-merchandise-total-one-input-sensitivity-table-d1f849d2 -d '<json body>'
```

Example prompt: Run a sensitivity table on my buy-2-get-1-free deal — baseline is 10 basket units, unit price $25, 2 paid per group, 1 free per group — and vary the basket_units across 8, 9, 10, 11, 12 to show me how the merchandise total changes.

## When to prefer this

Choose this endpoint when you need a quick, cheap one-variable what-if analysis for a Buy-X-get-Y-free retail promotion and have all baseline parameters on hand. It is ideal for merchandising teams or pricing agents that want to scan a range of basket sizes, unit prices, or group compositions without building a full spreadsheet model. Not suitable when you need multi-variable sensitivity, live market rates, or order execution.

## Known failure modes

- Values array exceeds 50 items — request rejected
- baseline missing required fields (basket_units, paid_units_per_group, free_units_per_group, unit_price) — validation error
- paid_units_per_group set to 0 — minimum is 1, returns error
- numeric values outside allowed bounds (±1,000,000,000,000) — rejected
- invalid field enum value — must be one of basket_units, paid_units_per_group, free_units_per_group, unit_price
