## 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 molcloud-web-browse-url-to-markdown-extractor-614dfb87
```

Example prompt: Can you fetch the content of https://example.com/article and give it to me as clean markdown text so I can read and summarize it?

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve and read the contents of a specific webpage as clean, LLM-ready Markdown without setting up browser infrastructure. It is ideal for single-URL lookups where you need human-readable text extraction with a token count — particularly in agentic pipelines that pay per-call in USDC via x402 and want zero-setup web access. Prefer this over full crawlers when you only need one page, and over raw HTTP fetchers when the page requires JavaScript rendering or you want pre-cleaned Markdown output.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Paywalled or bot-blocked pages may return incomplete or empty markdown
- Pages with heavy JavaScript rendering may not fully extract
- Missing required 'url' query parameter causes request failure
- x402 payment failure results in 402 response before content is returned
- Very large pages may produce high token counts that exceed downstream context limits
