## 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 pennyrail-text-stats-line-count-7ff8b4cd -d '<json body>'
```

Example prompt: Count how many lines are in this text: 'Hello world\nThis is line two\nAnd this is line three'

## When to prefer this

Choose this endpoint when you need a quick, cheap, pay-per-call line count for arbitrary text strings without managing your own parsing logic. It is especially useful in agent pipelines that process variable text blobs and need reliable line counts as a computational step without spinning up infrastructure.

## Known failure modes

- Missing 'input' field returns a validation error
- Empty string may return zero or an error depending on service behavior
- Very large text inputs may time out or be rejected
- Network or payment settlement failure returns HTTP 402 or 5xx
