## 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-trim-7aea3bd4 -d '<json body>'
```

Example prompt: Can you normalize and trim the newlines in this text for me: "Hello\n\n\nWorld\n\r\n"?

## When to prefer this

Choose this endpoint when you need a simple, deterministic, no-LLM newline normalization and trim on a text string and are willing to pay $0.01 USDC per call. Prefer the free unpaid POST /v1/sandbox/newline-trim endpoint first if available. Use this paid endpoint when the sandbox is unavailable or when you need guaranteed SLA.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment failure (insufficient USDC) results in 402 response
- Malformed request body returns a 400 error

## How this service works

Call when an agent needs newlines normalized to trim. No network and no LLM. Send JSON {"text":"Hello, World!"}. Exact $0.01 USDC on Base. Try unpaid POST /v1/sandbox/newline-trim first.

## Output

The cleaned text string with newlines normalized and trimmed, returned as a structured response. No external network calls or LLM processing are involved; the transformation is deterministic and purely computational.
