## 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 scrooge-x402-link-graph-extractor-d198fdb6
```

Example prompt: Can you pull all the outbound links from https://news.ycombinator.com — give me the href and anchor text for each one, up to 50 links?

## When to prefer this

Choose this endpoint when you need to enumerate outbound hyperlinks from a specific public HTML page, especially for SEO audits, content graph mapping, or link discovery workflows. It is purpose-built for link extraction with anchor text, unlike general page scrapers that return raw HTML or plain text. Prefer it over full-page content extractors when you specifically need href/anchor-text pairs rather than readable body text.

## Known failure modes

- Private or link-local URLs (e.g. 192.168.x.x, localhost) are blocked for SSRF safety
- Non-public or non-http(s) URLs will be rejected
- Pages with no outbound links return count: 0 and empty links array
- Heavily JavaScript-rendered pages may return fewer links than expected (static HTML only)
- maxLinks values outside 1–50 are clamped to the valid range
- Payment failure results in 402 response requiring 0.03 USDC on Base

## How this service works

Extract the outbound link graph of a public HTML page: final url, title, unique links as {href, text?}, and count. POST JSON {"url":"https://example.com","maxLinks":50}. Optional maxLinks is an integer 1–50 (default 50). Skips #, javascript, mailto, tel, and data links. Public http(s) only. $0.03 USDC on Base (eip155:8453). No API key.

## Output

Returns a JSON object with: `url` (final URL after redirects), `title` (HTML page title or null), `links` (array of up to 50 objects each with `href` and optional `text` anchor), and `count` (total number of unique links returned). Fragment (#), javascript:, mailto:, tel:, and data: links are excluded.
