## 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 newline-lf-final-normalizer-16b06a6b -d '<json body>'
```

Example prompt: Can you normalize all the line endings in this text to LF (Unix-style) and make sure it ends with a final newline? Here's the text: 'Hello\r\nWorld\r\nFoo\r\n'

## When to prefer this

Choose this endpoint when you need a fast, deterministic, offline text normalization with no LLM overhead and no network calls. Ideal for pipeline preprocessing steps where consistent LF line endings and a trailing newline are required. Use the free sandbox POST /v1/sandbox/newline-lf-final first; fall back to this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment of exactly $0.001 USDC required; missing or incorrect payment returns 402
- Malformed JSON body returns a 400 error

## How this service works

Call when an agent needs newlines normalized to lf-final. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/newline-lf-final first.

## Output

Returns the input text with all line endings converted to LF (\n), including mixed CRLF (\r\n) and bare CR (\r), and ensures the text concludes with a final LF character.
