## 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 pet-care-calc-food-portion-calculator-fa31822a
```

Example prompt: My dog needs 1,200 kcal per day and his kibble has 3,500 kcal per kg — can you figure out how many grams per meal I should feed him, split across 3 meals, keeping 10% of calories for treats?

## When to prefer this

Use this endpoint when you already have a pet's daily calorie requirement (e.g. from the /daily-energy sibling endpoint) and a food label's energy density, and need precise per-meal portion sizes in multiple units. Prefer this over manual calculation when you want a treat allowance automatically deducted and results in both grams and cups simultaneously.

## Known failure modes

- Missing dailyKcal parameter returns a 400 error
- Neither kcalPerKg nor kcalPerCup provided causes an error
- treatPercent outside 0–30 range rejected
- meals value outside 1–8 range rejected
- Negative or zero calorie values are invalid

## How this service works

Grams, cups and per-meal portions of pet food from daily kcal and the food's kcal per kg or per cup, with a treat allowance.

## Output

Returns daily and per-meal food portions in grams, cups, and ounces, along with the calories allocated to treats, the adjusted food kcal after the treat budget, number of meals, and a human-readable summary with a veterinary disclaimer.
