## 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

```

Example prompt: Can you fetch the contact page at https://example.com/contact and extract all the email addresses and phone numbers listed there?

## When to prefer this

Choose this endpoint when you need to quickly harvest contact information (emails and phone numbers) from a specific public web page without building your own scraper. It is ideal for lead generation, journalism, or sales research workflows where you have a target URL and want structured contact data in one call.

## Known failure modes

- URL is unreachable or returns a non-200 status — no contacts returned
- Page uses JavaScript rendering only, so static fetch misses dynamically loaded contacts
- Page has no email or phone numbers — returns empty lists
- URL is blocked by robots.txt or rate-limiting — fetch fails
- Malformed or non-HTTP URL provided — request error
