How this service works
Favicon finder: a site's favicon and icon URLs. Input: a URL.
Output
A JSON object containing the queried URL, a 'favicon' field with the direct favicon URL (e.g. https://example.com/favicon.ico), an 'icons' object with any additional icon URLs found on the page, and a 'google_s2' field with the Google S2 service URL for the domain's favicon at 64px size.
Example use cases
Enrich link previews with site icons
“I'm building a bookmarks page and need the favicon for each site — can you fetch the favicon and icon URLs for https://www.notion.so so I can display it next to the link?”
Verify brand icon before embedding
“Before I embed the icon in our dashboard, can you look up the actual favicon URL for https://www.stripe.com and tell me what it resolves to?”
Aggregate icons for a curated directory
“I'm putting together a directory of crypto tools and need the favicon for https://www.coingecko.com — grab the direct favicon link and the Google S2 URL for me.”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/favicon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly resolve a website's favicon or icon URL from just a domain or page URL, especially when building link previews, browser-style tabs, site directories, or any UI that displays a small representative icon alongside a URL. It is preferable over manual scraping because it also provides the Google S2 fallback, ensuring you always have a usable icon even if the site's own favicon is missing.
Side effects
- URL is unreachable or returns an error — favicon field may be empty or null
- Site has no standard favicon.ico and no link tags — icons object may be empty
- Malformed or missing URL input — validation error returned
- Google S2 fallback URL is always generated but may not resolve if Google hasn't indexed the domain
- Rate limiting or timeout if the target site responds slowly
