## 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 one-engine-text-normalize-line-endings-t5-57ceaf6d -d '<json body>'
```

Example prompt: Can you normalize the line endings in this text I just scraped — it has a mix of CRLF and LF characters and I need it cleaned up before I pass it to my pipeline: "Hello\r\nWorld\nFoo\r\nBar"?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call solution to normalize line endings in text strings as part of an automated agent pipeline. It is ideal for preprocessing scraped content, user-submitted text, or documents with mixed Windows (CRLF), Unix (LF), or legacy Mac (CR) line endings before passing them to NLP models, diff tools, or storage systems. At $0.0025 USDC per call via x402 on Base, it suits high-frequency agentic workflows where a full text-processing library would be overkill.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty text field — may return error or pass-through
- Malformed JSON body — 400 bad request
- Payment not provided or insufficient — 402 Payment Required
- Network timeout on Cloudflare Worker edge

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the input text with all line endings normalized to a consistent format (typically LF), ready for downstream text processing pipelines.
