## 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 yruz-reverse-list-tool-63a2655f -d '<json body>'
```

Example prompt: Can you reverse the order of this list for me: 'apple, banana, cherry, date, elderberry'?

## When to prefer this

Use this endpoint when you need a simple, cheap ($0.002 USDC) programmatic way to reverse a text-based list or sequence without implementing the logic yourself. Best for lightweight automation pipelines that already use x402 micropayments.

## Known failure modes

- Missing or empty 'text' input field returns an error
- Malformed JSON request body causes a 400-level error
- Non-list or ambiguously structured text may produce unexpected reversal output
- Payment failure (x402) if USDC balance is insufficient
