## 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 unprice-link-extractor-587c4849
```

Example prompt: Can you fetch the page at https://example.com and give me a list of all the hyperlinks on it?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use extraction of all hyperlinks from a single web page without setting up your own scraping infrastructure. It is ideal for lightweight link auditing, sitemap seeding, or discovering referenced URLs from a known page. Prefer it over general-purpose scrapers when you only need the link list and not the full page content or structured data extraction.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — link list may be empty or error returned
- Page uses heavy JavaScript rendering — statically fetched HTML may not include dynamically injected links
- Invalid or malformed URL input — request rejected
- Page blocks automated fetching (bot protection) — may return empty or error
- Payment failure via x402 — request not processed

## How this service works

Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.

## Output

A JSON object containing the source URL that was fetched, the total count of links found, and an array of all hyperlink URLs extracted from the page's HTML.
