## 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-alphabetize-lines-559022ff -d '<json body>'
```

Example prompt: Can you alphabetize these lines for me? 'Mango
Apple
Banana
Cherry
Date'

## When to prefer this

Use this endpoint when you need a fast, pay-per-call, serverless text-line alphabetization without setting up your own sorting logic. Good for lightweight agent pipelines that need deterministic text ordering on demand without managing infrastructure.

## Known failure modes

- Empty input string returns an error or empty result
- Non-string input rejected due to schema validation
- Network timeout if payload is very large
- Payment failure (402) if USDC balance is insufficient
