Your A2A Agent Card Loads. Does Your Agent Answer?
We index 7,372 A2A agents and probe every one of them each day. 85.6% publish an Agent Card that loads and parses. Only 29.7% return a JSON-RPC answer at the endpoint that card points to. For more than half of the agents in our directory, the card loads and the call behind it gets no usable reply: an error page, a request for credentials, or nothing.
