## 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 apexapi-finance-tip-calculator-e670266b -d '<json body>'
```

Example prompt: Calculate the tip and total for a $127.50 restaurant bill with a 20% tip split among 4 people.

## When to prefer this

Use this endpoint when you need a quick server-side tip and bill calculation without maintaining local logic, especially in contexts where per-call USDC micropayment billing is acceptable and no API key management is desired.

## Known failure modes

- Missing or unparseable query string returns an error
- Non-numeric bill amounts cause computation failure
- Tip percentages outside valid range may return unexpected results
- Payment of 0.082329 USDC required per call; unpaid requests return HTTP 402
