Tools
| Tool | Description | Behaviour |
|---|---|---|
| countersignatory_get_order | 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. | Read-only |
| countersignatory_place_order | 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 two ways to pay: an x402 pay_url that takes USDC on Base in an X-PAYMENT header, for an agent with a wallet, and 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. | Changes data |
| countersignatory_quote | 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. | Read-only |
| countersignatory_register_interest | 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. | Changes data |
| 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. Use it for the reference rate table across all markets; use countersignatory_quote when you have a specific task and need a price for it. | Read-only |
