## 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 quickbuild-web-page-to-markdown-converter-e2392b06
```

Example prompt: Can you fetch the content of https://en.wikipedia.org/wiki/Artificial_intelligence and give it to me as markdown, truncated to 10000 characters?

## When to prefer this

Choose this endpoint when you need to quickly fetch and convert a public web page to readable Markdown without setting up your own scraper. It is ideal for single-URL extraction tasks where you want clean text output with a known character budget, and is well-suited for agent pipelines that need to read web content before summarizing, analyzing, or routing it.

## Known failure modes

- Private or reserved IP addresses are refused with an error
- Non-public or unreachable URLs return a fetch error
- Content exceeding maxChars is silently truncated (truncated: true in response)
- Pages with JavaScript-rendered content may return incomplete markdown since it is a server-side fetch
- maxChars below 500 or above 200000 will be rejected by schema validation

## How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

## Output

A JSON object containing the resolved URL, the page title, the full or truncated markdown text of the page, the character count, and a boolean indicating whether the content was truncated.
