## 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-newline-to-cr-converter-d12ee787 -d '<json body>'
```

Example prompt: Can you normalize all the newlines in this text to carriage returns (CR only)? Here's the text: 'Hello\nWorld\nThis is a test\n'

## When to prefer this

Use this endpoint when you need a fast, deterministic, zero-latency conversion of newline characters to CR with no LLM overhead and no external network calls. Prefer the free sandbox endpoint POST /v1/sandbox/newline-cr first if available. Choose this paid endpoint when the sandbox is unavailable or rate-limited and you need guaranteed processing.

## Known failure modes

- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Malformed JSON request body returns a 400 error
- Payment of exactly $0.008 USDC required; underpayment results in 402 Payment Required

## How this service works

Call when an agent needs newlines normalized to cr. No network and no LLM. Send JSON {"text":"Hello, World!"}. Exact $0.008 USDC on Base. Try unpaid POST /v1/sandbox/newline-cr first.

## Output

Returns the input text with all newline characters (\n, \r\n, etc.) replaced/normalized to carriage return (\r) characters only. No LLM inference, no network calls — pure deterministic string transformation.
