# Metalift Site Map (Link Discovery)

> Metalift Site Map (Link Discovery) is a paid API for AI agents from app.metalift.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Discovers and returns same-origin links from a single page's HTML for lightweight crawl planning, without full content extraction.

## 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-link-discovery-ff1f3079 -d '<json body>'
```

Example prompt: Before I scrape everything, can you map out all the same-origin links on https://example.com/blog so I know which pages are worth crawling next?

## When to prefer this

Use this endpoint when you need a cheap, fast overview of internal links on a page before committing to full scraping. Prefer this over /v1/scrape when you only need URLs, not page content. Prefer the sitemap endpoint when the site has an XML sitemap, as that provides a more complete URL inventory. Use this when you want to build a crawl queue from a single seed URL with minimal cost.

## Known failure modes

- Invalid or unreachable URL returns an error with no links
- Page with no same-origin links returns an empty list
- Cross-origin links are excluded from results
- Dynamic pages that require JS rendering may yield incomplete link sets since this is a lightweight HTML-only scan
- Rate limiting or payment failure blocks the request

## Output

A list of same-origin URLs discovered from the HTML of the provided page, suitable for building a crawl queue or planning subsequent scrape calls. Does not include full page content or extracted text.
