Revenue Bridge Documentation Update\n\n```markdown\n# oneworld_trade/docs/INN_REVENUE_BRIDGE.md (Connection 2 Update)\n\n## Connection 2: FINN + River Integration\n\n### Revenue Flow\n- FINN enabled: $0.10-0.50 per landed cost calculation\n- River freight data integration adds value\n- Complexity-based pricing model\n\n### Pricing Tiers\n- Basic calculation: $0.10 (single mode, standard commodity)\n- Complex calculation: $0.50 (multi-modal, special commodity, high value)\n\n### Integration Points\n1. River watermarks → FINN freight input\n2. FINN calculate() → Complete landed cost\n3. Shop /landed-cost → Customer endpoint\n4. Metering based on calculation complexity\n\n### Revenue Metrics\n- Target: $50-200 per user/month\n- Usage patterns: 100-400 calculations/user/month\n- Premium features: Real-time rates, optimization suggestions\n```\n\n## 6. Usage Example\n\n```bash\n# Test the new endpoint\ncurl -X POST \"http://localhost:8000/shop/landed-cost\" \\\n  -H \"Authorization: Bearer YOUR_TOKEN\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"origin_port\": \"CNSHA\",\n    \"destination_port\": \"USLAX\", \n    \"commodity_code\": \"8471.30.01\",\n    \"fob_value\": 25000.00,\n    \"weight_kg\": 500,\n    \"volume_cbm\": 2.5,\n    \"currency\": \"USD\"\n  }'\n```\n\n**Response:**\n```json\n{\n  \"fob_value\": 25000.00,\n  \"freight_cost\": 1250.00,\n  \"insurance_cost\": 78.75,\n  \"duty_amount\": 1575.00,\n  \"fees_total\": 450.00,\n  \"landed_cost_total\": 28353.75,\n  \"currency\": \"USD\",\n  \"breakdown\": {\n    \"watermarks_used\": [...],\n    \"complexity_factors\": {...}\n  }\n}\n```\n\nThis implementation enables FINN, creates the Shop endpoint, wires River freight data, and implements the complexity-based metering system as specified in the revenue bridge documentation."
