## 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 creator-desk-line-count-utility-fed8c1a0 -d '<json body>'
```

Example prompt: Can you count how many lines are in this text block: 'Hello world
This is line two
And line three'?

## When to prefer this

Choose this endpoint when an AI agent needs a quick, paid-per-use line count computation on a text value without setting up local string processing logic. Useful in agent pipelines where metered utility calls are preferred over inline code execution, or when orchestrating tasks via x402-compatible payment infrastructure.

## Known failure modes

- Missing or null 'value' field may return an error or zero result
- Non-string value types passed without proper coercion may cause unexpected results
- Empty string input may return zero or one depending on implementation
- Payment failure via x402 protocol will block the call before execution
- Network timeout if the hosted Render.com instance is cold-starting
