## 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 24k-labs-html-to-markdown-converter-443027e8 -d '<json body>'
```

Example prompt: Take this HTML snippet I have and convert it to clean Markdown — strip out any scripts, nav, and styling but keep the headings, bold, links, lists, and code blocks intact.

## When to prefer this

Choose this endpoint when you already have an HTML string in memory and need it converted to Markdown without making an additional HTTP fetch — it is a pure transformation, not a scraper. Ideal for processing HTML from CMS exports, scraped content, or API responses when you need clean, readable Markdown output for documentation, LLM context, or plain-text pipelines.

## Known failure modes

- Malformed or unparseable HTML may produce incomplete or garbled Markdown output
- Very large HTML payloads may exceed size limits or time out
- HTML with no semantic content (pure script/style) returns an empty or minimal Markdown string
- Nested or deeply complex table structures may not convert perfectly to Markdown

## How this service works

Convert a supplied HTML string to clean Markdown: strips scripts/style/nav, preserves headings, bold, italic, links, lists, code, and blockquotes. No fetch.

## Output

A clean Markdown string derived from the input HTML, with scripts, styles, and navigation removed, and semantic elements (headings, bold, italic, links, lists, code blocks, blockquotes) preserved as proper Markdown syntax.
