User submits a property address through the chat interface.\n2. The AI Agent queries Zillow for a rent Zestimate.\n3. The agent converts the property zipcode to a CBSA code via the HUD USPS lookup tool.\n4. Using the CBSA code, the agent queries HUD Fair Market Rent for bedroom-matched rates.\n5. The agent queries Rentometer for local rent comps.\n6. A formatted rental analysis table is returned in the chat.\n\n### Setup\n- [ ] Add your Apify API key (uses the `maxcopell/zillow-detail-scraper` actor)\n- [ ] Register for a free HUD API key at [huduser.gov](https://www.huduser.gov/hudapi/public/register) and add as HTTP Bearer credential\n- [ ] Add your Rentometer API key as an HTTP Bearer credential\n- [ ] Connect your OpenAI API key to the OpenAI Chat Model node\n\n### Customization\nSwap `gpt-4.1-mini` for a more powerful model if analysis quality needs improvement." }, "typeVersion": 1 }, { "id": "4a943030-3d2a-4ca5-8463-edb45cd61c80", "name": "Warning Note", "type": "n8n-nodes-base.stickyNote", "position": [ 832, -544 ], "parameters": { "width": 460, "height": 100, "content": "\u26a0\ufe0f **All three API keys must be configured before running.**\nMissing credentials will cause the AI Agent to fail silently or return incomplete data." }, "typeVersion": 1 }, { "id": "68d93474-d161-4d74-a4b2-17374d371a88", "name": "Agent Section", "type": "n8n-nodes-base.stickyNote", "position": [ 448, -544 ], "parameters": { "color": 7, "width": 360, "height": 340, "content": "## \ud83d\udcac Chat Interface & AI Agent\nReceives the property address from the user and orchestrates all tool calls in the correct order.\n\n## \ud83d\udd27 Rental Data Tools\nFour tools available to the AI Agent.
