## 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 24k-labs-extract-links-db868e58 -d '<json body>'
```

Example prompt: Can you fetch https://example.com/blog and give me all the hyperlinks on that page — only external ones?

## When to prefer this

Use this endpoint when you need a fast, lightweight extraction of all hyperlinks from a single web page without needing full page content or structured data. It is ideal for link auditing, SEO analysis, outbound link research, or building simple site maps. Prefer this over a full-page scraper when you only need URLs, not the surrounding text or HTML structure.

## Known failure modes

- Page is unreachable or returns a non-200 status — endpoint may return an error or empty list
- Page requires JavaScript rendering — static fetch may miss dynamically injected links
- URL is malformed or missing — likely returns a validation error
- Page blocks bots or returns a CAPTCHA — link extraction may be empty or fail
- Very large pages with thousands of links may incur latency or truncation

## How this service works

Fetch a page and return all hyperlinks (absolute), optionally filtered to external only.

## Output

A list of absolute hyperlink URLs found on the fetched page. If the external-only flag is set, only links pointing to domains other than the source page are returned. Each entry is a fully qualified URL string.
