Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-case-insensitive-line-sorter-5241d865 -d '<json body>'
```

Example prompt: Sort these lines of text alphabetically, ignoring uppercase and lowercase differences: 'Banana
Apple
cherry
date
ELDERBERRY'

## When to prefer this

Use this endpoint when you need a deterministic, server-side case-insensitive line sort without any local compute — particularly useful in agent pipelines that run in sandboxed environments with no access to shell utilities like `sort -f`. If a free sandbox endpoint at POST /v1/sandbox/lines-sort-ci is available, prefer that first to avoid the $0.008 USDC charge.

## 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 causes a 402 response
- Network unreachable or service downtime returns a 5xx error

## How this service works

Call when an agent needs lines of text transformed with sort-ci. No network. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/lines-sort-ci first.

## Output

Returns the input text with all lines reordered in case-insensitive ascending alphabetical order, preserving original line content (including original casing of each line).
