## 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-syntexa-ch-css-footer-extractor-e0b83df1 -d '<json body>'
```

Example prompt: Can you extract the footer text from https://example.com for me? I need to see what links and legal text are in that page's footer.

## When to prefer this

Use this endpoint when you need to extract footer content from a public webpage or known HTML and want SSRF-safe fetching. It is the paid fallback when the free sandbox endpoint (/v1/sandbox/css-footer) is unavailable or quota-exhausted. Prefer it over general-purpose scrapers when you specifically need footer text and want a lightweight, purpose-built extraction rather than a full-page crawl.

## Known failure modes

- URL is unreachable or returns non-200 status — extraction fails
- URL points to internal/private network addresses — blocked by SSRF protection
- HTML input exceeds 200,000 character limit — rejected
- No footer element found in the page — empty or null result
- Malformed URL (fewer than 8 characters) — validation error
- Rate limiting or payment failure on x402 protocol

## How this service works

Call when an agent needs footer text via footer from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/css-footer first.

## Output

Returns the extracted footer text found in the CSS footer section of the provided webpage URL or raw HTML content, including any copyright notices, navigation links, legal disclaimers, or contact information present in the footer.
