## Payment Flow

### x402 Bot Payment (Multi-Chain)
1. Bot requests tool → receives 402 Payment Required
2. 402 response lists ALL 13 chains + facilitators + tokens
3. Bot pays on ANY supported chain (USDC, USDT, BTC, EUR, etc.)
4. Bot includes `X-Pay` header with payment proof
5. Smart router auto-picks best facilitator for that chain/token
6. Payment verified → tool executes → result returned
7. If facilitator fails, router auto-falls to next best

### Router Logic
- Chain match → Bot pays on TRON → MERX TRON handles it
- Token match → Bot pays USDT → Pieverse on BSC, MERX on TRON
- Health → Unhealthy facilitators skipped
- Priority → Fee-free > instant > deferred
- Auto-fallback → CDP quota exceeded → PayAI takes over

### Human Payment (Web)
1. User connects wallet (Phantom, MetaMask, WalletConnect, Coinbase Wallet)
2. Selects tool and payment method (USDC-SOL, USDC-Base, SOL, ETH, USDT)
3. Signs transaction in wallet
4. Payment verified on-chain via appropriate facilitator
5. Tool executes, result displayed

### Trial Mode
Each tool has 1-5 free trial calls. No payment needed for initial testing.
