## 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-food-quantity-calculator-0f694615
```

Example prompt: How much main-course boneless meat do I need for a party of 75 guests, where 15 are kids, assuming kids eat half an adult portion and we expect big appetites so use a multiplier of 1.3?

## When to prefer this

Use this endpoint when you need a quick, formula-driven food quantity estimate for a specific course type at an event. It is ideal for party planners, caterers, or anyone organizing a meal who needs to account for a mix of adults and children with customizable portion sizes and appetite levels. Prefer this over generic recipe calculators when you need per-course breakdown with kid-adjustment logic built in.

## Known failure modes

- Missing required 'guests' or 'type' parameters returns a validation error
- Guest count outside 1–5000 range is rejected
- Invalid food type string not matching supported enum values causes error
- kidFactor outside 0.1–1 range rejected
- Multiplier outside 0.25–5 range rejected
- Payment failure (x402) prevents response if USDC balance insufficient

## How this service works

Food to prepare for a guest count by course (appetizer, main, side, salad, dessert, bread) with kid and appetite multipliers.

## Output

Returns the total food amount in the appropriate unit (e.g. pounds, ounces, pieces), broken down by per-adult amount, effective adult portions, raw total, and a rounded-up quantity for purchasing. Also includes a human-readable summary, unit label, any relevant disclaimers, and metadata like the food type, guest count, kid count, kid factor, and multiplier used.
