# Favicon Finder: Site Icons and Sizes

> Favicon Finder: Site Icons and Sizes is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Fetches all favicon and icon links from a webpage (including rel=icon, apple-touch-icon, mask-icon, web manifest, and /favicon.ico), returning each as an absolute URL with size and type, plus the single best icon selected automatically.

## 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 agent-data-tools-revmesh2074-workers-dev-favicon-finder-site-icons-04038e48
```

Example prompt: Can you find all the icons and favicons for stripe.com and tell me which one is the best to use as a logo thumbnail — ideally an SVG or the largest available size?

## When to prefer this

Use this endpoint when you need to visually represent a website with its official icon — for link previews, bookmarks, company directories, or CRM enrichment. It is preferable to scraping HTML manually because it handles all icon rel variants, resolves relative URLs to absolute ones, checks /favicon.ico automatically, and applies a best-pick algorithm (SVG > largest size, excluding mask icons) so you don't need custom selection logic.

## Known failure modes

- Site is unreachable or times out — no icons returned
- Site blocks crawlers and returns 403/401 — empty or partial icon list
- Page has no icon tags at all — empty icons array with faviconIco: false
- Relative URLs on malformed pages may not resolve correctly
- Dynamic SPAs that load icons via JavaScript may not be detected
- Manifest JSON linked in page may exist but not be fetched/parsed

## How this service works

Find a website's icons: every <link rel=icon>, shortcut icon, apple-touch-icon and mask-icon on the page with its size and type, the web app manifest link, and whether /favicon.ico exists, all as absolute URLs, with the best icon picked (SVG, then the largest size; mask icons never). Use to show a site's logo next to a link, build bookmarks or enrich a company record.

## Output

Returns a JSON object with the original URL, the automatically selected best icon URL (SVG preferred, otherwise largest non-mask icon), an array of all discovered icons each with rel type, absolute href, MIME type, and sizes attribute, the web app manifest URL if found, and a boolean indicating whether /favicon.ico exists at the root.
