## 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-web-page-to-markdown-reader-2b951520
```

Example prompt: Can you fetch the content of https://docs.x402.org/introduction and return it as markdown so I can read through it?

## When to prefer this

Choose this endpoint when you need to read a single public web page's content as clean Markdown or plain text without executing JavaScript, and want structured metadata (title, language, word count, links) alongside the content. Ideal for documentation reading, article extraction, and content preprocessing for LLMs. Prefer this over full browser automation when JavaScript rendering is not required and speed matters.

## Known failure modes

- URL is unreachable or returns a non-200 status — status field reflects the HTTP error code
- robots.txt disallows crawling — the endpoint respects robots.txt and may return empty or restricted content
- JavaScript-rendered content is not captured — the fetcher does not execute JavaScript
- Content exceeds maxChars limit — content is truncated and truncated flag is set to true
- Invalid or malformed URL provided — request fails with a validation error
- Payment not completed via x402 — request blocked before fetching
