## 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 party-event-planner-pizza-order-calculator-91f24e43
```

Example prompt: How many 16-inch pizzas should I order for 40 guests, 8 of whom are kids? Assume 3 slices per adult, 2 per child, 8 slices per pizza, and add 10% extra — also compare against a 12-inch size.

## When to prefer this

Use this endpoint when you need a precise, parameterized pizza quantity calculation for a mixed adult-and-child guest list, especially when you want area-based size comparisons, cost totals, and a configurable extra-order buffer — as opposed to a generic rule-of-thumb estimate.

## Known failure modes

- Missing required 'guests' parameter returns an error
- guests outside 1–5000 range may return a validation error
- diameterIn outside 6–36 range may be rejected
- slicesPerPizza outside 2–24 range may be rejected
- extraPercent outside 0–100 range may be rejected
- Payment failure (402) if USDC not provided or insufficient

## How this service works

How many pizzas to order from guests, kids and slices each, with pizza area, area per guest and a size comparison.

## Output

Returns the number of pizzas to order, total slices needed, spare slices, area per guest in square inches, total pizza area, a size comparison between two diameters, optional total cost, and a human-readable summary and verdict.
