## 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 netintel-markdown-cleaner-6a98dd05 -d '<json body>'
```

Example prompt: Can you clean up this messy markdown for me and tell me how much it was reduced and what quality grade it gets? Here's the raw text: '# My Doc

Hello [world](https://example.com).

<div>some html junk</div>'

## When to prefer this

Use this endpoint when you need to programmatically clean, sanitize, or assess the quality of markdown text — especially markdown scraped from the web or generated by AI that may contain HTML noise, redundant whitespace, or structural issues. Prefer this over generic text-cleaning tools when you specifically need markdown-aware processing with a quality grade and reduction metrics.

## Known failure modes

- Missing or empty markdown body returns an error
- Malformed POST body results in a 400-level response
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Extremely large inputs may time out or be rejected
- Non-markdown or binary input may return low scores or unexpected findings

## How this service works

Convert messy HTML or text into clean, well-structured Markdown using Claude Haiku — strips boilerplate, fixes heading hierarchy, normalizes lists and links, and returns readable Markdown so agents can feed clean docs into downstream pipelines, knowledge bases, or LLM context.

## Output

Returns a JSON object with: the cleaned markdown string, a letter grade (e.g. 'A'), a numeric score (0-100), a boolean indicating if the result was cached, an array of findings (issues detected), and character counts for input and output along with a reduction ratio (e.g. 0.64 meaning 64% reduction).
