Wire Alchemy into application code without an API key, using the x402 or MPP gateway with wallet-based auth (SIWE/SIWS) and per-request payments (USDC via x402, or USDC/credit-card via MPP). Specialized app-integration path. Use when the user is building application code AND no API key is available, or they're an autonomous agent that needs to pay for itself, or they explicitly want x402/MPP.
