## 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 agentic-market-site-brief-vercel-app-64a64afa
```

Example prompt: Can you pull a quick brief on https://stripe.com — I want the page title, main headings, key links, and whether the site has any API or pricing language on it?

## When to prefer this

Choose this endpoint when you need a lightweight, structured snapshot of a public webpage — especially when assessing whether a site exposes API, docs, pricing, or contact surfaces for agent workflows. Prefer this over full-page scrapers when you only need metadata, headings, and top-level links without full HTML content.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error or empty fields
- Private/intranet URLs that are not publicly accessible will fail to load
- Very large or JavaScript-heavy pages may return incomplete headings or links
- Malformed URL input causes schema validation failure
- Rate limiting or network timeouts may cause intermittent failures

## How this service works

## Output

Returns the requested URL, final URL after redirects, page title, meta description, excerpt, list of headings, list of href/text link pairs, and an agentSignals object indicating boolean flags for hasApiLanguage, hasDocsLanguage, hasContactLanguage, and hasPricingLanguage.
