Choose this endpoint when you need pay-per-call access to Base mainnet JSON-RPC without managing your own node or maintaining a subscription — especially useful for AI agents making sporadic on-chain queries that don't justify a dedicated RPC plan, and when you are already using x402 micropayments for other Surplus Intelligence services.
