## 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-suffix-lines-utility-a0630876 -d '<json body>'
```

Example prompt: Take this list of product names and add ' [SALE]' to the end of every line: 'Widget A
Widget B
Widget C'

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01 USDC), machine-callable utility to append a suffix to every line of a text block without spinning up your own text processing logic. It's ideal for autonomous agents that need lightweight string transformation as part of a larger workflow, especially when operating in an x402 micropayment environment.

## Known failure modes

- Missing or null 'value' field returns an error or empty result
- Non-string value input may cause unexpected behavior
- Payment failure via x402 protocol blocks the request before processing
- Malformed options object may be ignored or cause a 400 error
- Very large input text may hit payload or processing limits

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output
