## 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-reverse-lines-utility-f127c0c4 -d '<json body>'
```

Example prompt: Reverse the line order of this text for me: 'First line
Second line
Third line
Fourth line' — I need the lines flipped so the last line comes first.

## When to prefer this

Choose this endpoint when you need a simple, reliable, pay-per-call line-reversal utility within an x402 micropayment workflow — especially useful in autonomous agent pipelines where you want a lightweight, stateless text transformation without spinning up your own processing logic.

## Known failure modes

- Empty or null 'value' input may return an error or empty result
- Non-string or non-line-delimited input may produce unexpected output
- Payment failure (402) if x402 micropayment is not correctly handled
- Malformed JSON request body returns a 400-level error
- Service unavailability on Render free-tier cold starts may cause timeout

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

A JSON object containing a 'result' field with the input text lines reordered in reverse sequence, and an 'operation' field confirming 'reverse_lines'. The reversed text preserves each line's content but inverts their top-to-bottom order.
