## 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 genesis-link-extractor-31c411ae -d '<json body>'
```

Example prompt: Can you extract all the HTTP and HTTPS links from https://example.com/blog and give me a normalized list of every URL you find on that page?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call link extraction from a single public URL without setting up your own crawler infrastructure. It is ideal for ad-hoc link discovery, sitemap seeding, or agent-driven web research workflows where you want normalized, clean URLs. Prefer it over full crawl services when you only need links from one page at a time and want minimal cost ($0.003/call).

## Known failure modes

- URL is not publicly accessible (returns 403/401) — extraction fails
- Target page returns non-HTML content (PDF, image, etc.) — no links extracted
- Network timeout reaching the target URL — request fails
- Malformed or invalid URL input — validation error returned
- JavaScript-rendered pages may yield incomplete link sets if JS is not executed
- Target site blocks crawlers via robots.txt or rate limiting

## How this service works

Extract and normalize HTTP and HTTPS links from a public web page. Use for crawlers, sitemap generation, link discovery, website structure analysis, research agents and web link extraction. Price: $0.003 USDC via x402 on Base.

## Output

A list of extracted and normalized HTTP and HTTPS URLs found on the target web page, deduplicated and ready for downstream processing such as crawling, sitemap generation, or link analysis.
