Choose this endpoint when you need a lightweight, pay-per-call LLM query without a subscription, especially when operating an autonomous agent that can pay micropayments in USDC on Base via x402. Ideal for sporadic queries where a flat subscription is wasteful, or when integrating AI search into a crypto-native workflow.
