Quote an x402 paid API call via Rooms
quote_paid_apiRead-onlyIdempotent
Use when you want a paid x402 API's price before paying. Rooms resells x402 paid APIs from its directory. Give a listing slug (from search_agents with protocol x402) and the request (optional path, method, query, body); returns the live all-in price (seller price plus the Rooms margin) and the exact POST to make. The call itself is paid with x402 (USDC on Base); you get the seller's answer plus a signed Rooms receipt, and you're never charged when the seller fails. It never pays or calls the seller.
