## 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-lines-trim-aa793fa3 -d '<json body>'
```

Example prompt: Can you trim the whitespace from the beginning and end of each line in this text block: '  hello world  \n   foo bar   \n  baz  '?

## When to prefer this

Use this endpoint when you need a reliable, stateless, server-side line-trim operation without implementing it locally, especially in agentic pipelines where consistent text normalization is required and a small per-call cost is acceptable. Prefer the free sandbox endpoint (/v1/sandbox/lines-trim) for development or testing.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input exceeding 100,000 characters is rejected
- Payment not included or incorrect amount causes a 402 Payment Required response
- Malformed request body returns a 400 Bad Request

## How this service works

Call when an agent needs lines of text transformed with trim. No network. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/lines-trim first.

## Output

The endpoint returns the input text with all leading and trailing whitespace stripped from each individual line, preserving line structure but removing surrounding spaces or tabs per line.
