# Implementation Summary - Full REST API with Auto Token Refresh
## 🎯 Problem Identified
You reported that despite running the service on port 9000 non-stop, tokens were still expiring. Investigation revealed:
### Root Cause
The service running on port 9000 was `tiger_rest_api.py`, a **simplified REST API** that:
- ❌ Has NO token refresh functionality
- ❌ Creates new Tiger client instances per request
- ❌ Doesn't use TokenManager from the MCP system
- ❌ Relies only on Tiger SDK's default 24h refresh (which doesn't work with per-request clients)
### Why Token Expired
```
tiger_rest_api.py running 24/7
↓
Each request creates new client
↓
Client destroyed after request
↓
SDK never lives long enough to trigger 24h refresh
↓
Token expires after 15 days
```
---
## ✅ Solution Implemented
Created `tiger_rest_api_full.py` with:
### 1. Automatic Token Refresh
- **Background task** runs every 12 hours
- **Tiger token lifecycle**: 15-day expiry, SDK refreshes at 24h intervals
- **Safety margin**: We use 12h to ensure tokens never expire
- **Mechanism**: Triggers Tiger SDK client, which auto-updates `tiger_openapi_token.properties`
### 2. Complete API Coverage
**Total: 22 Endpoints** across 5 categories:
#### System (2)
- `GET /health` - Health check
- `GET /api/endpoints` - List all endpoints
#### Account Management (2)
- `GET /api/accounts` - List accessible accounts
- `POST /api/token/refresh` - Manual token refresh (admin only)
#### Market Data (6)
- `POST /api/market/quote` - Real-time quotes
- `POST /api/market/kline` - Historical K-line data
- `POST /api/market/batch` - Batch quotes for multiple symbols
- `POST /api/market/search` - Search symbols by keyword
- `POST /api/market/option-chain` - Option chain data
- `POST /api/market/status` - Market trading hours/status
#### Company Info (4)
- `POST /api/info/contracts` - Contract details
- `POST /api/info/financials` - Financial statements
- `POST /api/info/corporate-actions` - Dividends, splits, mergers
- `POST /api/info/earnings` - Earnings calendar
#### Trading (6)
- `POST /api/trade/positions` - Current positions
- `POST /api/trade/account-info` - Account balance and metrics
- `POST /api/trade/orders` - Order history with filters
- `POST /api/trade/place-order` - Place new order (MKT/LMT/STP/STP_LMT)
- `POST /api/trade/modify-order` - Modify pending order
- `POST /api/trade/cancel-order` - Cancel order
### 3. Key Features
✅ **Multi-Account Support**
- 3 accounts configured: 2 live + 1 demo
- Granular permissions per API key
- Account isolation
✅ **API Key Authentication**
- Bearer token authentication
- Role-based access (read/trade/admin)
- Configurable permissions
✅ **Production Ready**
- CORS enabled for web apps
- Comprehensive error handling
- Detailed logging
- Health monitoring

## 🔄 Token Refresh Architecture
```
Server Startup
↓
Background task started
↓
Wait 1 minute (initialization)
↓
First token refresh
├─ Account 1: Tiger SDK triggered → token updated
├─ Account 2: Tiger SDK triggered → token updated
└─ Account 3: Tiger SDK triggered → token updated
↓
Every 12 hours:
├─ Refresh all accounts
├─ SDK auto-updates tiger_openapi_token.properties
└─ Retry on error (1h backoff)
↓
Token valid indefinitely ♾️
```
### How It Works
1. **Background Task**: Runs in asyncio event loop
2. **Per-Account Refresh**: Creates Tiger client per account
3. **SDK Auto-Update**: Tiger SDK updates token file automatically
4. **Shared Token File**: All instances read from same file
5. **Error Handling**: Exponential backoff on failures

## 🚀 Usage
### Starting the Server
```bash
# Stop running instance (if any)
pkill -f tiger_rest_api_full.py || true
# Start API
cd /home/trader/tiger-mcp
python tiger_rest_api_full.py
# Or in background
nohup python tiger_rest_api_full.py > rest_api_full.log 2>&1 &
```
### Making Requests
```bash
# Health check (no auth)
curl http://localhost:9000/health
# List accounts (auth required)
curl -H "Authorization: Bearer client_key_001" \
http://localhost:9000/api/accounts
# Get quote
curl -X POST http://localhost:9000/api/market/quote \
-H "Authorization: Bearer client_key_001" \
-H "Content-Type: application/json" \
-d '{
"account": "67686635",
"symbol": "AAPL"
}'
# Place order
curl -X POST http://localhost:9000/api/trade/place-order \
-H "Authorization: Bearer client_key_001" \
-H "Content-Type: application/json" \
-d '{
"account": "67686635",
"symbol": "AAPL",
"action": "BUY",
"order_type": "LMT",
"quantity": 100,
"limit_price": 175.00
}'
```

## ⚠️ Important: Initial Setup
Since your token has already expired, you need to:
1. **Regenerate token** from Tiger Brokers website
2. **Download** new `tiger_openapi_token.properties`
3. **Replace** old token file
4. **Restart** the API server
5. **Verify** auto-refresh is working (check logs)
After this one-time setup, tokens will **never expire** as long as the server runs.

## 📈 Monitoring
### Check Server Status
```bash
# Health endpoint
curl http://localhost:9000/health
# Check if running
ps aux | grep tiger_rest_api_full
```
### Monitor Token Refresh
```bash
# View logs
tail -f rest_api_full.log
# Look for these messages:
✅ Background token refresh scheduler started
🔄 Starting scheduled token refresh for all accounts...
✅ Token refresh successful for account 67686635
⏰ Next token refresh in 12.0h
```
### Manual Token Refresh
```bash
# Emergency refresh via API
curl -X POST http://localhost:9000/api/token/refresh \
-H "Authorization: Bearer client_key_001" \
-H "Content-Type: application/json" \
-d '{
"account": "67686635"
}'
```
