BIMI Checker

bimi-checker.underscoredone.com · x402

Checks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple Mail, and Yahoo. It looks up the BIMI settings the domain has published, checks the logo file follows the required format, checks any logo certificate is valid and unexpired, and confirms the domain has strict enough email protection turned on. Returns a clear pass or fail per domain, plus a plain list of what is broken when something fails.

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read . addrbook has not counted these payments itself.
