Favicon finder: a site's icons and their sizes

$0.01 per call · failed calls are never charged · no account or API key needed

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.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/url/favicon?url=https%3A%2F%2Fgithub.com%2F"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/url/favicon?url=https%3A%2F%2Fgithub.com%2F&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
