## 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 machine-shop-html-to-markdown-converter-d88a6b6e -d '<json body>'
```

Example prompt: Can you convert this HTML snippet into Markdown for me? Here's the HTML: '<h1>Hello</h1><p>This is a <a href="/docs">link</a>.</p>' — use 'https://example.com' as the base URL so relative links resolve correctly.

## When to prefer this

Choose this endpoint when you need a reliable, pay-per-call HTML-to-Markdown conversion without setting up your own parser. Ideal for agents that scrape or receive HTML content and need clean Markdown for LLM ingestion, document comparison, or field extraction. Prefer it over general-purpose scrapers when you already have the raw HTML and just need the format conversion step.

## Known failure modes

- HTML input exceeds 50,000 character limit — request rejected
- Invalid or malformed base_url — links may not resolve correctly
- Empty or null HTML input — returns empty or minimal Markdown
- Malformed HTML that cannot be parsed — output Markdown may be incomplete or garbled
- Payment not provided or insufficient — x402 payment required error
