Icon Horse vs Metropolitan Museum of Art

Icon Horse fetches the favicon for any given domain — trying the site's own icon first and falling back through a chain of alternate sources so a usable image is returned almost every time — with no signup. A live GET against the real host returned a genuine PNG carrying Access-Control-Allow-Origin: *, reconfirming both auth None and cors yes.

The Met's Collection API exposes all 502,000+ objects in its Open Access collection — the same data behind its own site — fully keyless and free, asking only that callers self-throttle to 80 requests per second. A live GET against the real gateway, collectionapi.metmuseum.org, returned genuine object data carrying Access-Control-Allow-Origin: *, correcting cors no -> yes while reconfirming auth None.
