## 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 product-specification-whitespace-normalisation-6861e432 -d '<json body>'
```

Example prompt: Can you clean up the whitespace in this product spec — it has inconsistent spacing and stray blank lines throughout the Markdown?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC), deterministic whitespace clean-up for product specification documents in Markdown or plain text, without any generative rewriting or fact-checking. Ideal for preprocessing docs before review cycles, version control commits, or automated documentation pipelines where consistency matters but content should not change.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — no output produced
- Malformed request body — API returns error
- Network timeout for very large inputs near the character limit
