I’m generating link previews and I need an automated way to fetch icons for many domains via an API.

Provide an API that automatically retrieves website icons (such as favicons) for a given domain or URL. This helps you generate consistent, polished link previews without manually sourcing and maintaining icon assets.

This feature offers an automated API for fetching site icons for many domains to support link preview generation. Instead of manually downloading, storing, and updating favicons or brand icons, you can request an icon by supplying a domain or full URL. The service resolves the appropriate icon source, retrieves an available icon, and returns it in a predictable way suitable for UI rendering. This reduces the time spent handling edge cases such as missing favicon files, nonstandard icon locations, or sites with multiple icon variants. It also improves consistency across link previews by standardizing how icons are discovered and delivered. The API can be integrated into your backend pipeline that builds preview cards, or called on-demand when rendering previews in a client application. It is especially useful when you need to support many domains at scale and want to avoid maintaining a curated icon database. Typical use cases include social sharing previews, bookmarking tools, chat applications, feed readers, and internal dashboards that display external links. Overall, it streamlines icon retrieval so you can focus on preview content and user experience rather than asset collection.
