## 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-no-final-normalizer-c9ad00d3 -d '<json body>'
```

Example prompt: Can you clean up this text by removing any trailing newlines from the end? Here's the text: 'Hello world
This is my content
'

## When to prefer this

Use this endpoint when you need a deterministic, no-LLM, no-network operation to strip trailing newlines from text strings up to 100KB. Prefer the free sandbox endpoint POST /v1/sandbox/newline-no-final for testing or when you want to avoid the $0.002 USDC cost. Choose this paid endpoint for production pipelines where 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 $0.002 USDC not provided or insufficient results in 402 Payment Required
- Malformed request body returns 400 Bad Request

## How this service works

Call when an agent needs newlines normalized to no-final. No network and no LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/newline-no-final first.

## Output

Returns the input text with any trailing newline characters removed from the end, producing a clean string with no final newline. The response is the normalized text string.
