## 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-favicon-apple-touch-icon-extractor-4b23736e -d '<json body>'
```

Example prompt: Can you extract the favicon and apple-touch icon URLs from https://example.com for me?

## When to prefer this

Use this endpoint when you need to programmatically extract favicon or apple-touch icon metadata from a public webpage URL or raw HTML in an SSRF-safe manner. Prefer the free sandbox endpoint POST /v1/sandbox/favicon-meta for testing before paying. Choose this over general web scraping tools when you specifically need icon/favicon data without exposing your infrastructure to SSRF attacks.

## Known failure modes

- URL is private/internal (SSRF blocked) — returns error indicating blocked request
- URL is unreachable or returns non-2xx — returns fetch error
- HTML provided is malformed or has no icon link tags — returns empty icon set
- Input exceeds maxLength constraints — returns validation error
- Both url and html fields omitted — returns bad request error

## How this service works

Call when an agent needs favicon and apple-touch icons extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/favicon-meta first.

## Output

Returns extracted favicon and apple-touch icon metadata from the provided URL or HTML, including icon URLs, sizes, and types found in the page's link tags and standard icon locations.
