per call · USD Coin on Base
Fetch a site's favicon/logo: reads the page's declared <link rel=icon…> tags (all variants with their sizes and types), deterministically picks the largest declared icon (falling back to /favicon.ico), fetches it, and returns the bytes as a base64 data URI plus the resolved icon URL and content type. Icons over 256KB return the URL and metadata without the inline data URI. SSRF-guarded - private-network hosts are rejected. Sites with no reachable icon return {found:false}.
