## Description

Ask Fortytwo high-complexity questions where the best answer is required — coding, architecture, hard reasoning, and more. Request Fortytwo MCP `tools/call` for `ask_fortytwo_prime` through the payment-gated gateway, which uses the extended x402 payment protocol with on-chain escrow to enable usage-based, pay-per-token billing for AI services. This requires access to a web3 wallet with USDC on Base or Monad. The first call triggers a payment challenge; subsequent calls within the same session are free.
