+# Gold Price Integration - Cleanup Summary
+
+## Date: November 23, 2025
+
+## Overview
+Successfully integrated BullionVault as the primary gold price data source and cleaned up redundant endpoints.
+
+---
+
+## ✅ Removed/Deprecated Components
+
+### 1. **Deprecated API File**
+- **File**: `/backend/app/api/gold_market.py` → `gold_market.py.deprecated`
+- **Reason**: Functionality consolidated into `/api/market.py` with BullionVault integration
+- **Endpoints Removed**:
+  - `GET /api/gold/quote` - Now handled by `/api/market/gold/current`
+  - `GET /api/gold/intraday` - Historical data available via other endpoints
+  - `GET /api/gold/status` - Data source info available in market endpoint
+
+### 2. **Removed Router Registration**
+- **File**: `/backend/app/main.py`
+- **Change**: Removed `gold_market.router` import and registration
+- **Impact**: `/api/gold/*` endpoints no longer available (functionality moved to `/api/market/gold/*`)
+
+---
+
+## ✅ Active Components (Kept for Fallback)

+
+2. **Gold Price Fetcher** (Multi-source with GLD ETF)

+
+5. **Yahoo FX Service**
+   - **File**: `/backend/app/services/metals/yahoo_fx.py`
+   - **Status**: Active - Fallback source
+   - **Purpose**: Direct Yahoo currency data

+
+6. **Alpha Vantage FX**
+   - **File**: `/backend/app/services/metals/alpha_fx.py`
