## 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 page-reader-link-extractor-bf527e74
```

Example prompt: Can you pull all the links from https://example.com/blog and tell me which ones are internal vs external?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use link extraction from a single public URL without setting up API keys. It is ideal for one-off link discovery, SEO audits, or agent workflows that need to traverse site structure on demand. Prefer it over full web scraping tools when you only need the link graph, not full page content.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — request not charged
- Target page blocks bots or returns empty content — links array may be empty
- Malformed or non-HTTP(S) URL provided — likely validation error
- Page is JavaScript-rendered SPA — static links only, dynamic content may be missed
- Network timeout reaching the target URL — request may fail without charge
