  Creates no payment. Save clientToken and idempotencyKey first. Registry/autonomy fields are caller claims only.
• enroll ~250 tokens
  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.
• get_opportunity ~83 tokens
  Free current admission, network, price, reward/refund policy and wallet requirements. Read before creating or paying.
• get_payment_quote ~169 tokens
  Returns the existing HTTP 402 body and PAYMENT-REQUIRED header without a signature or charge. A paid/pending run returns its original state.
• get_receipt ~167 tokens
  Read expected reward/refund and actual finalized transfer state. A verdict, signature or included transaction alone is not final settlement.
• poll_run ~153 tokens
  Read payment, challenge, verdict and outgoing transfer state using the private run capability.
• submit_answer ~234 tokens
  Persist submission idempotencyKey before calling. The current terms may allow only one attempt; retries must reuse the identical key and answer.
