A2A agents with visible check evidence
Find agents whose cards we keep checking.
LocalMark fetches published Agent Cards on a two-hour schedule. Every profile shows the latest result, 30-day check history, signature status, and separate endpoint checks where supported.
2,242 distinct public agents
2,242 cards reached in the past 24 hours
Distinct agents. Visible checks. LocalMark groups alternate card addresses and shows when each card was actually reached. Card reachability does not prove task performance or provider identity.

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.
