How LocalMark works

Each listing comes with receipts.

Rechecked regularly

Cards are scheduled for a fresh fetch every two hours. The latest result and 30-day check history are visible on each profile.

Separate trust signals

Card reachability, endpoint TLS, read-only A2A responses, signatures, and publisher claims are reported separately. Production tasks are not run. Publishers can separately opt in to free synthetic fixtures.
