## 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 x402-agent-data-utility-web-links-extractor-7ad9819b -d '<json body>'
```

Example prompt: Can you pull all the hyperlinks from https://example.com/blog and give me the list of URLs found on that page?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-request link extraction from a single URL without standing up your own scraping infrastructure. It is ideal for AI agents that need to discover outbound links on demand and can pay $0.002 USDC per call via x402. Prefer alternatives if you need full-page content extraction, JavaScript rendering, or bulk crawling.

## Known failure modes

- Target URL is unreachable or returns non-200 status — empty links array or error response
- Malformed or missing URL input — request fails with validation error
- Target page uses heavy JavaScript rendering that prevents static link extraction — links array may be incomplete
- Payment not attached or insufficient — x402 payment required error
- Rate limiting or blocking by target server — fetch failure

## How this service works

Pay-per-request data tools for AI agents.

## Output

Returns a JSON object with ok: true and a data.links array containing the hyperlinks extracted from the target webpage. Each entry in the links array represents a URL or anchor found on the page.
