## 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 agentshelf-lines-sort-descending-d152e432 -d '<json body>'
```

Example prompt: Sort these lines of text in descending (Z-to-A) order: 'banana
apple
cherry
date'

## When to prefer this

Use this endpoint when you need server-side descending sort of text lines without implementing sorting logic locally, especially in agent workflows where a quick paid microservice call is acceptable. Prefer the free sandbox endpoint POST /v1/sandbox/lines-sort-desc first if available.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment failure or insufficient USDC balance prevents processing
- Network errors or service unavailability return 5xx responses

## How this service works

Call when an agent needs lines of text transformed with sort-desc. No network. Send JSON {"text":"b\na\n"}. Exact $0.008 USDC on Base. Try unpaid POST /v1/sandbox/lines-sort-desc first.

## Output

Returns the input text with all lines reordered in descending (reverse lexicographic / Z-to-A) order, preserving line content but sorting their sequence from largest to smallest.
