## 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 cerwal-link-extractor-71fc9d14 -d '<json body>'
```

Example prompt: Can you extract all the links from https://example.com/blog for me? I need every URL 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 with no auth setup or subscription required. Ideal for AI agents that need ad-hoc web scraping without managing API keys, especially in x402-compatible payment environments.

## Known failure modes

- URL is unreachable or returns a non-200 status — success: false
- URL is malformed or missing — validation error
- Target page blocks scraping (bot detection, CAPTCHA) — empty or partial results
- Payment via x402 fails — request rejected before execution
- Page has no links — data returns empty link list

## How this service works
