## How to call it through Zero

```sh
zero fetch --capability cake-servings-calculator-472a5a85
```

Example prompt: How many servings will I get from a 3-tier round cake with tiers sized 6, 8, and 10 inches, cut in wedding style?

## When to prefer this

Use this endpoint when you need to compute cake servings from pan dimensions — especially for multi-tier or wedding cakes where slice style (wedding vs party) matters. Prefer this over generic food quantity calculators when the input is pan shape and size rather than a guest count, or when you need tier-by-tier breakdowns for a stacked cake design.

## Known failure modes

- Missing required 'shape' or 'sizeIn' parameters returns an error
- Invalid shape value (not round, square, or rectangle) may cause a bad request
- Rectangle shape without 'widthIn' parameter may return an error or incomplete result
- Malformed tier list (non-numeric values in comma-separated sizeIn) may cause a parse error
- Conflicting sliceStyle and servingSqIn parameters may produce unexpected results

## How this service works

Cake servings from pan size and area per slice: round, square or rectangle, one or several tiers, wedding or party slice style.

## Output

Returns total servings across all tiers, per-tier breakdowns (size, top area, servings), the slice style and area per slice used, a human-readable summary and verdict, and an optional disclaimer. Degraded flag indicates if any tier calculation was skipped.
