Server tool list (7)
Raw names from tools/list. Only developers need these.
| 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 | 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 | 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. |
