Prepare a SuperBlock purchase reservation. Requires API key with purchase:prepare scope. Flags off: returns the legacy non-executing purchaseIntent with contract address, USDC amount, chain ID, and purchase ID. ADA-36 flags on: also returns an HTTP 402 payment-required envelope for x402-compatible payment negotiation, paidAction intentId, settle endpoint, and receipt endpoint. Settlement requires a direct SuperblockPurchaseRouter.purchase(...) transaction followed by canonical PoolParty receipt verification. This tool does not sign or broadcast a transaction. Reservations expire in 15 minutes.
