## 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 keyronne-web-to-markdown-converter-52337bb3 -d '<json body>'
```

Example prompt: Grab the article at https://example.com/article and convert it to clean markdown — I need the full readable content plus the title, description, and any Open Graph tags so I can feed it into my LLM pipeline.

## When to prefer this

Use this endpoint when an AI agent needs to ingest web content as LLM-ready text — particularly when you need both cleaned Markdown and structured metadata (OG tags, canonical URL, language) in a single call. Prefer this over generic scraping tools when the goal is readable prose for an LLM rather than raw HTML or structured data extraction.

## Known failure modes

- URL is unreachable or returns a non-200 status — API returns an error indicating the fetch failed
- HTML exceeds 2 MB limit — request rejected with size-limit error
- URL points to a private/internal network address — blocked for security reasons
- Malformed JSON body or missing both url and html fields — validation error returned
- Page has no meaningful content (e.g. pure JavaScript SPA with empty server-side HTML) — returns sparse or empty markdown

## How this service works

Convert a web page (by URL) or raw HTML into clean, readable Markdown plus structured metadata (title, description, Open Graph tags, canonical URL, language). Strips scripts, styles and boilerplate tags; preserves headings, links, images, lists, code blocks and tables. Built for agents that need web content as LLM-ready text. POST a JSON body like: {"url":"https://example.com/article"}

## Output

Returns clean Markdown text of the page content with scripts, styles, and boilerplate removed, plus structured metadata: title, meta description, Open Graph tags, canonical URL, and detected language.
