## 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 primeapi-finance-tip-calculator-db7608aa -d '<json body>'
```

## Known failure modes

- Missing or malformed query string returns generic API error
- Invalid numeric values in query cause computation failure
- Ambiguous query with no parseable bill amount returns empty or incorrect result
- Service unavailability returns 402 or 5xx error requiring retry
