## 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 agent402-tools-sort-lines-cda926a7 -d '<json body>'
```

Example prompt: Sort these lines alphabetically in descending order and remove any duplicates: 'Banana\nApple\nCherry\nApple\nDate' — treat it as case-insensitive.

## When to prefer this

Use this endpoint when you need a simple, reliable server-side line sort with configurable direction, numeric awareness, deduplication, and case-insensitivity — especially when you want to avoid implementing sorting logic client-side or need consistent behavior across platforms.

## Known failure modes

- Empty or missing text field returns an error
- Invalid order value (not asc/desc/numeric) may return a validation error
- Very large text inputs may time out or exceed payload limits
- Non-numeric lines when using numeric sort may produce unexpected ordering

## How this service works

Sort the lines of a text. order: asc (default) | desc | numeric. unique:true removes duplicates; ci:true is case-insensitive.

## Output

Returns the input text with lines reordered according to the specified sort order (asc, desc, or numeric). Duplicate lines are removed if unique=true. Comparison is case-insensitive if ci=true.
