Is countersignatory live?

Yes — it answered the hub's last check (checked 1h ago). It answered 98% of checks over the last 30 days.

Is countersignatory free to use?

Not measured yet.

What tools does countersignatory have?

5 tools: countersignatory_quote, countersignatory_register_interest, countersignatory_place_order, countersignatory_get_order, countersignatory_spot_index.

Is countersignatory 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.

• countersignatory_quote reads unknown never probed

  Get the current spot price to have a verified human check, agree on, sign off or notarise something. Use when an agent needs human judgment, accountability or a signature, and needs to know the cost and time before committing. Returns an indicative price, a band, what would clear at a lower bid, and the implied rate per human minute.

• countersignatory_register_interest changes data unknown never probed

  Record that you would buy. Send the quote_id from a countersignatory_quote response to say the quoted price would clear your use case. For a market on the spot index whose state is opening, which cannot be quoted yet, send its market id instead. This is the demand signal that decides which markets open first.

• countersignatory_place_order moves money unknown never probed

  Buy one task from a verified human in a market whose state is live on the spot index: an approval (should this action go ahead), a verification (does this page, document or screenshot show X), or a judgment (which is better, or which label applies). The order is priced at current spot and created unpaid; nothing is charged by this call. The response carries a checkout_url a person can open to pay by card. Once paid it is answered by hand within the SLA, or refunded in full. Read the answer with countersignatory_get_order. Refused at intake: CAPTCHAs and bot checks, logging in or entering credentials, contacting third parties, medical, legal or financial advice, anything sexual or involving minors.

• countersignatory_get_order reads unknown never probed

  Read one order by the id countersignatory_place_order returned: its status (awaiting_payment, paid, in_progress, answered, refused, refunded or expired), its price, how to pay while it is unpaid, and once answered the answer, the reason, and who gave it and how they are disclosed. A consensus order returns each responder's answer and the majority.
