+# FastAPI Modernization Summary
+
+## 🎯 **Issue Fixed**
+FastAPI `on_event` decorators were deprecated in favor of lifespan event handlers. This was causing deprecation warnings in the logs.
+
+## ✅ **Services Modernized**
+
+### 1. Agent Registry Service
+- **File**: `/opt/aitbc/apps/agent-services/agent-registry/src/app.py`
+- **Change**: Replaced `@app.on_event("startup")` with `@asynccontextmanager` lifespan
+- **Status**: ✅ Complete
+
+### 2. Agent Coordinator Service  
+- **File**: `/opt/aitbc/apps/agent-services/agent-coordinator/src/coordinator.py`
+- **Change**: Replaced `@app.on_event("startup")` with `@asynccontextmanager` lifespan
+- **Status**: ✅ Complete
+
+### 3. Compliance Service
+- **File**: `/opt/aitbc/apps/compliance-service/main.py`
+- **Change**: Replaced both startup and shutdown events with lifespan handler
+- **Status**: ✅ Complete
+
+### 4. Trading Engine
+- **File**: `/opt/aitbc/apps/trading-engine/main.py`
+- **Change**: Replaced both startup and shutdown events with lifespan handler
+- **Status**: ✅ Complete
+
+### 5. Exchange API
+- **File**: `/opt/aitbc/apps/exchange/exchange_api.py`
+- **Change**: Replaced `@app.on_event("startup")` with lifespan handler
+- **Status**: ✅ Complete
+
+## 🔧 **Technical Changes**
+
+### Before (Deprecated)
+```python
+@app.on_event("startup")
+async def startup_event():
+    init_db()
+
+@app.on_event("shutdown") 
+async def shutdown_event():
+    cleanup()
+```
+
+### After (Modern)
+```python
+@asynccontextmanager
+async def lifespan(app: FastAPI):
+    # Startup
+    init_db()
+    yield
+    # Shutdown
+    cleanup()
+
+app = FastAPI(..., lifespan=lifespan)
+```
+
+## 📊 **Benefits**
+
+1. **Eliminated deprecation warnings** - No more FastAPI warnings in logs
+2. **Modern FastAPI patterns** - Using current best practices
+3. **Better resource management** - Proper cleanup on shutdown
+4. **Future compatibility** - Compatible with future FastAPI versions
+
+## 🚀 **Testing Results**
+
+All services pass syntax validation:
+- ✅ Agent registry syntax OK
+- ✅ Agent coordinator syntax OK  
+- ✅ Compliance service syntax OK
+- ✅ Trading engine syntax OK
+- ✅ Exchange API syntax OK
+
+## 📋 **Remaining Work**
+
+There are still several other services with the deprecated `on_event` pattern:
+- `apps/blockchain-node/scripts/mock_coordinator.py`
+- `apps/exchange-integration/main.py`
+- `apps/global-ai-agents/main.py`
+- `apps/global-infrastructure/main.py`
+- `apps/multi-region-load-balancer/main.py`
+- `apps/plugin-analytics/main.py`
+- `apps/plugin-marketplace/main.py`
+- `apps/plugin-registry/main.py`
+- `apps/plugin-security/main.py`
+
+These can be modernized following the same pattern when needed.
