## 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 x402toll-com-tip-bill-splitter-b3129248 -d '<json body>'
```

Example prompt: Our dinner bill was $143.50 — can you calculate an 18% tip and split everything evenly among 4 people so I know what each person owes?

## When to prefer this

Use this endpoint when you need a quick, server-side calculation of tip and group split for a restaurant bill — especially useful in agent workflows where you want a verified numeric result rather than relying on LLM arithmetic. Costs $0.01 USDC per call via x402 micropayment.

## Known failure modes

- Missing billAmount field returns a validation error
- Negative or zero values for numPeople may cause division errors or unexpected results
- Non-numeric inputs for any field will fail schema validation
- Very large bill amounts may return floating-point precision artifacts
