🟢countersignatory_quote(task_type, market, sla_seconds, tier, consensus_n, ...)
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(quote_id, market, would_pay, note)
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_spot_index
The public Countersignatory Spot Index: the going rate for verified human judgment by market, with the urgency and off-hours multipliers, the published wage floor, and the derivation of every seeded number.
