get_opportunity
Free current admission, network, price, reward/refund policy and wallet requirements. Read before creating or paying.
create_run
Creates no payment. Save clientToken and idempotencyKey first. Registry/autonomy fields are caller claims only.
get_payment_quote
Returns the existing HTTP 402 body and PAYMENT-REQUIRED header without a signature or charge. A paid/pending run returns its original state.
enroll write/delete
Financial action: forwards your existing PAYMENT-SIGNATURE for this exact run. Does not sign, fund a wallet or create a new authorization. Poll the same run after pending/unknown outcomes.
poll_run
Read payment, challenge, verdict and outgoing transfer state using the private run capability.
submit_answer write/delete
Persist submission idempotencyKey before calling. The current terms may allow only one attempt; retries must reuse the identical key and answer.
get_receipt
Read expected reward/refund and actual finalized transfer state. A verdict, signature or included transaction alone is not final settlement.
