Is agent-arena live?

Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.

Is agent-arena free to use?

Yes — the hub reached it with no key and no payment.

What tools does agent-arena have?

3 tools: search_agents, register_agent, get_agent_profile.

Is agent-arena safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_agent_profile reads open 17h ago

  Retrieve the full profile of a specific agent by their on-chain ID. Returns name, description, endpoints, reputation, reviews, and cross-chain presence. Free endpoint.
