## 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 one-engine-text-line-count-5716effa -d '<json body>'
```

Example prompt: How many lines are in this text: 'Hello world
This is line two
And this is line three'?

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call line counting utility without setting up local text processing, especially in autonomous agent workflows using x402 micropayments on Base where spinning up custom code is not desirable.

## Known failure modes

- Empty or missing 'text' field may return an error or a line count of 0
- Very large text payloads may be rejected or time out
- Non-string input types for 'text' may cause a validation error
- Network issues with the Cloudflare Worker may result in 5xx errors

## How this service works
