## 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 metalift-site-map-same-origin-link-discovery-3646ef7d -d '<json body>'
```

Example prompt: Before scraping the whole site, can you list all the internal links found on https://example.com/blog so I know which pages to crawl next?

## When to prefer this

Use this endpoint when you need a fast, cheap inventory of internal links on a page before committing to full scrapes. Prefer it over /v1/scrape when you only need navigation structure, not page content. Prefer it over /v1/sitemap when the site lacks an XML sitemap or you want page-level link discovery rather than site-wide XML parsing.

## Known failure modes

- Invalid or unreachable URL returns an error with no links
- External-only pages return an empty link list if no same-origin anchors exist
- JavaScript-rendered navigation links may not be captured if JS rendering is not applied
- Rate limiting or WAF blocks on the target page may prevent link discovery
- Malformed URL input fails schema validation

## How this service works

Metalift site map: same-origin link discovery from one page's HTML (no full extraction). Use for lightweight crawl planning before /v1/scrape. (1 credit ≈ $0.002 USDC)

## Output

A list of same-origin anchor URLs found in the HTML of the requested page, suitable for planning subsequent scrape or crawl operations. No full page content or markdown is returned — just discovered internal links.
