## 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-syntexa-ch-text-norm-trim-lines-98b44d92 -d '<json body>'
```

Example prompt: Can you trim the leading and trailing whitespace from every line in this text block: '  Hello World  \n  foo bar  \n   baz  '?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, pure-compute line-trimming normalization with no LLM or external network calls. It is ideal when you want a guaranteed exact result (not AI-generated), need low latency, and want to avoid LLM inference costs. Prefer the free sandbox endpoint /v1/sandbox/norm-trim-lines first if available.

## Known failure modes

- Empty or missing text field returns a validation error
- Text exceeding 100,000 characters is rejected
- Malformed JSON body returns a parse error
- Payment of exactly $0.004 USDC required; incorrect payment amount causes payment failure

## How this service works

Call when an agent needs text normalized with trim-lines. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/norm-trim-lines first.

## Output

Returns the input text with leading and trailing whitespace stripped from every line, preserving line structure but removing extraneous spaces and tabs at line boundaries.
