## 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 sitecheck-html-to-clean-markdown-converter-26cb6a74 -d '<json body>'
```

Example prompt: Take this raw HTML from the product page and convert it to clean markdown — use https://example.com/products as the base URL so relative links become absolute.

## When to prefer this

Choose this endpoint when you have raw HTML that needs to be sanitised and converted to human- or LLM-readable markdown, especially when you want boilerplate (scripts, styles, nav, footers, forms, comments) stripped away. It is ideal for preprocessing scraped web pages before passing content to a language model, or when relative links need resolving against a known base URL. Prefer it over generic HTML-strippers when GitHub-flavoured Markdown formatting (headings, code blocks, lists, images) must be preserved.

## Known failure modes

- HTML input exceeds 500,000 characters — request rejected
- Missing or empty html field — validation error returned
- Malformed base URL causes relative link resolution to fail silently or error
- Extremely nested or malformed HTML may produce garbled markdown output
- Tables are flattened to plain text, losing tabular structure

## How this service works

Converts raw HTML you send (up to 500 KB) to GitHub-flavoured Markdown: headings, paragraphs, links, images, lists, code blocks, quotes, bold and italic. Scripts, styles, navigation, footers, forms and comments are removed; tables are flattened to text. Relative links need a base URL to become absolute.

## Output

A JSON object containing the original HTML source, the optional base URL used, the converted GitHub-flavoured Markdown string (with headings, paragraphs, links, images, lists, code blocks, blockquotes, bold, and italic preserved), a checkedAt ISO timestamp, and the character count of the resulting markdown.
