## 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-e3809f87 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call way to extract all hyperlinks from a single web page without managing a headless browser or scraping infrastructure. It is ideal for one-off link audits, SEO analysis, competitive research, or feeding discovered URLs into a larger crawl pipeline. Prefer it over full-page scraping endpoints when only the link graph (not page content or structured data) is needed.

## Known failure modes

- Page is behind authentication or a paywall — returns empty or partial link list
- URL is unreachable or returns non-200 status — endpoint returns an error response
- Page uses JavaScript-rendered links that are not present in static HTML — those links may be missed
- Malformed or non-HTTP URL input — validation error returned
- Rate limiting or bot-blocking by the target site — fetch may fail or return incomplete content

## 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. When the external-only filter is applied, only links pointing to domains different from the source page are included. Each result is a fully-qualified URL string.
