## 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 coco-tip-split-calculator-8bcb332a
```

Example prompt: We just finished dinner and the bill is $100, there are 4 of us, tax is 8%, and we want to tip 18% — can you calculate how much each person owes?

## When to prefer this

Use this endpoint when you need a quick, deterministic server-side calculation of tip, tax, and per-person split for a restaurant bill. Prefer this over doing the arithmetic yourself when you want consistent rounding behavior or when embedding tip-split logic in a larger agent workflow without writing custom math.

## Known failure modes

- Missing required parameters (bill, people, tax_pct, tip_pct) may return incomplete or error response
- Non-numeric string values passed as query params may cause computation errors
- Division by zero if people=0
- Negative or nonsensical values may produce unexpected numeric results
