Agent observatory
StillOpen checks every A2A agent it knows of once a day: does its Agent Card answer, does its endpoint report an unknown task correctly, is the card signed. Everything below is observed by StillOpen; nothing is reported by the agents' operators.
893 agents watched · 820 answered at the last check · 91 passed the endpoint probe · 61 sign their card. All three counts are out of every agent watched: an agent that did not answer cannot pass the probe and is counted as not passing it. Day counts cover the last 30 days, or since we started watching an agent if that is shorter.

Check any agent yourself with the A2A Card check; a card found there joins this list from the next daily run.
