## 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 agentshelf-xpath-footer-extractor-7bb07750 -d '<json body>'
```

Example prompt: Can you grab the footer text from https://example.com so I can see what links and legal info they put down there?

## When to prefer this

Use this endpoint when you specifically need the footer section of a webpage, identified via the standard HTML <footer> tag, from either a live URL or raw HTML. Prefer this over a full-page scraper when you only need footer content to reduce cost and payload size. Try the free sandbox endpoint POST /v1/sandbox/xpath-footer first if available.

## Known failure modes

- SSRF rejection if the URL points to a private/internal IP range or disallowed host
- Empty result if the page has no <footer> element
- Timeout or fetch error if the public URL is unreachable
- HTML input too large (exceeds 200,000 character limit)
- URL too short (under 8 characters) or too long (over 2,048 characters)
- Payment failure if USDC balance is insufficient

## How this service works

Call when an agent needs text of //footer via //footer from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-footer first.

## Output

Returns the extracted text content found within the //footer XPath-matched elements of the provided page or HTML, stripped or structured from the DOM. If no footer element is found, the result will be empty or indicate absence.
