Is signcheck live?

Yes — it answered the hub's last check (checked 49m ago). It answered 100% of checks over the last 30 days.

Is signcheck free to use?

Not measured yet.

What tools does signcheck have?

3 tools: signcheck_redeem, signcheck_verify, signcheck_pricing.

Is signcheck 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.

  把爱发电订单上的提取码换成 AK（entitlement）：带可用次数与有效期，由卖家私钥签名，可直接用 /seller-key.jwk 自验。不收费；一张码只能换一次，AK 绑定到你这次签证明的 keyid。换到后把 entitlement 传给 signcheck_verify 即可。

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
