Dev easter egg: let your AI agent tip via x402
A real x402 endpoint: calling without payment returns a 402 challenge; an agent signs a 1-cent payment (Base Sepolia testnet USDC for now) and retries. No accounts, no API keys.
curl -i /api/tip/thanks # → 402 + PAYMENT-REQUIRED 头（base64 挑战） # agent 签名付款后带 X-PAYMENT 头重试 → 200
Testnet phase: do not send mainnet funds via x402; switching to Base mainnet once validated.
