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 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.

Argument	Type	Description
input*	object	The task. approval: {action, context (up to 20,000 characters), urls? (up to 5), policy?}. verification: {claim, evidence: {url}, instructions?}. judgment: {item, labels (2 to 10)} or {pair: [a, b], labels?}, with an optional rubric.
market*	string	The id of a market whose state is live on the spot index, e.g. check.general or consensus.3.general. Pass the id verbatim.
template*	string	approval: answers approve or reject. verification: answers true, false or cannot_tell. judgment: answers one label. Every answer comes with a reason.
max_price*	number	The most you will pay, in USD. If the price is above it the order is refused and nothing is charged.
sla_seconds*	integer	Seconds from payment to answer. 86400 is the base price; a shorter deadline costs more. Not answered in time is refunded in full.
webhook_url	string	An https URL that receives the order on every status change.
