|
||||||
|
|
||||||
|
🏠 **Sophisticated FastAPI proxy server for the Rentcast API with intelligent caching, rate limiting, and cost management.**

|
||||||
|
## ✨ Features
|
||||||
|
|
||||||
|
### 🚀 **Performance & Caching**
|
||||||
|
- **Intelligent Multi-Level Caching**: SQLite for persistence + optional Redis for speed
|
||||||
|
- **Configurable TTL**: Different cache durations for different endpoint types
|
||||||
|
- **Stale-While-Revalidate**: Serve cached data during upstream failures
|
||||||
|
- **Cache Warming**: Pre-populate cache for better performance
|
||||||
|
- **Soft Deletion**: Mark entries invalid instead of deleting for analytics
|
||||||
|
|
||||||
|
### 💰 **Cost Management**
|
||||||
|
- **Usage Tracking**: Monitor API costs and savings from cache hits
|
||||||
|
- **Rate Limiting**: Prevent expensive API overuse with per-endpoint limits
|
||||||
|
- **Cost Estimation**: Track estimated costs for each endpoint type
|
||||||
|
- **Budget Alerts**: Monitor spending against configured limits
|
||||||
|
|
||||||
|
### 🔐 **Security & Access Control**
|
||||||
|
- **API Key Management**: Create, update, and revoke access keys
|
||||||
|
- **Role-Based Access**: Different limits per API key
|
||||||
|
- **Rate Limiting**: Global and per-endpoint request limits
|
||||||
|
- **CORS Support**: Configurable cross-origin resource sharing
|
||||||
|
- **Request Validation**: Comprehensive input validation with Pydantic
|
||||||
|
|
||||||
|
### 📊 **Analytics & Monitoring**
|
||||||
|
- **Real-time Metrics**: Cache hit ratios, response times, error rates
|
||||||
|
- **Usage Statistics**: Track usage patterns and popular endpoints
|
||||||
|
- **Health Checks**: Monitor system and dependency health
|
||||||
|
- **Structured Logging**: JSON logs for easy parsing and analysis
|
||||||
|
|
||||||
|
### 🔧 **Developer Experience**
|
||||||
|
- **OpenAPI Docs**: Auto-generated API documentation
|
||||||
|
- **CLI Administration**: Command-line tools for management
|
||||||
|
- **Type Safety**: Full type annotations with Pydantic models
|
||||||
|
- **Comprehensive Tests**: Unit and integration test coverage
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|

### Basic Usage
|
||||||
|
|
||||||
|
1. **Start the server**:
|
||||||
|
```bash
|
||||||
|
# Using CLI
|
||||||
|
rentcache server
|
||||||
|
|
||||||
|
# Or directly
|
||||||
|
uvicorn rentcache.server:app --reload
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Create an API key**:
|
||||||
|
```bash
|
||||||
|
rentcache create-key my_app YOUR_RENTCAST_API_KEY
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Make API calls**:
|
||||||
|
```bash
|
||||||
|
curl -H "Authorization: Bearer YOUR_RENTCAST_API_KEY" \
|
||||||
|
"http://localhost:8000/api/v1/properties?city=Austin&state=TX"
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Check metrics**:
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8000/metrics"
|
||||||
|
```
|
||||||
|
|
||||||

|
||||||
|
### Core Endpoints
|
||||||
|
|
||||||
|
All Rentcast API endpoints are proxied with intelligent caching:
|
||||||
|
|
||||||
|
#### 🏘️ **Property Records**
|
||||||
|
```http
|
||||||
|
GET /api/v1/properties
|
||||||
|
GET /api/v1/properties/{property_id}
|
||||||
|
```
|
||||||
|
**Cache TTL**: 24 hours (expensive endpoints)
|
||||||
|
|
||||||
|
#### 💲 **Value & Rent Estimates**
|
||||||
|
```http
|
||||||
|
GET /api/v1/estimates/value
|
||||||
|
GET /api/v1/estimates/rent
|
||||||
|
POST /api/v1/estimates/value/bulk
|
||||||
|
POST /api/v1/estimates/rent/bulk
|
||||||
|
```
|
||||||
|
**Cache TTL**: 1 hour (dynamic pricing)
|
||||||
|
|
||||||
|
#### 🏠 **Listings**
|
||||||
|
```http
|
||||||
|
GET /api/v1/listings/sale
|
||||||
|
GET /api/v1/listings/rental
|
||||||
|
GET /api/v1/listings/{listing_id}
|
||||||
|
```
|
||||||
|
**Cache TTL**: 30 minutes (frequently updated)
|
||||||
|
|
||||||
|
#### 📈 **Market Data**
|
||||||
|
```http
|
||||||
|
GET /api/v1/markets/stats
|
||||||
|
GET /api/v1/comparables
|
||||||
|
```
|
||||||
|
**Cache TTL**: 2 hours (market statistics)
|
||||||
|
|
||||||
|
### Cache Control Parameters
|
||||||
|
|
||||||
|
All endpoints support these parameters:
|
||||||
|
|
||||||
|
- `force_refresh=true`: Bypass cache and fetch fresh data
|
||||||
|
- `ttl_override=3600`: Override default TTL (in seconds)
|
||||||
|
|
||||||
|
### Response Headers
|
||||||
|
|
||||||
|
Every response includes cache information:
|
||||||
|
|
||||||
|
```http
|
||||||
|
X-Cache-Hit: true|false
|
||||||
|
X-Response-Time-MS: 45.2
|
||||||
|
X-Estimated-Cost: 2.0 (only on cache misses)
|
||||||
|
```
|
||||||
|
|
||||||
|

|

|
```
|
||||||
|
|
||||||
|
### Cache Strategy
|
||||||
|
|
||||||
|
1. **L1 Cache (Redis)**: Fast in-memory cache for frequently accessed data
|
||||||
|
2. **L2 Cache (SQLite/PostgreSQL)**: Persistent cache with analytics and soft deletion
|
||||||
|
3. **Cache Keys**: MD5 hash of endpoint + method + parameters
|
||||||
|
4. **TTL Management**: Different expiration times based on data volatility
|
||||||
|
5. **Stale-While-Revalidate**: Serve expired data during upstream failures
|
||||||
|
|
||||||
|
### Rate Limiting Strategy
|
||||||
|
|
||||||
|
1. **Global Limits**: Per API key across all endpoints
|
||||||
|
2. **Per-Endpoint Limits**: Specific limits for expensive operations
|
||||||
|
3. **Exponential Backoff**: Automatically slow down aggressive clients
|
||||||
|
4. **Usage Tracking**: Monitor and alert on approaching limits
|
||||||
|
|
||||||
|

## 📊 Monitoring & Analytics
|
||||||
|
|
||||||
|
### Key Metrics
|
||||||
|
|
||||||
|
- **Cache Hit Ratio**: Percentage of requests served from cache
|
||||||
|
- **Response Times**: Average response time by endpoint
|
||||||
|
- **Error Rates**: 4xx/5xx error percentages
|
||||||
|
- **Cost Tracking**: Estimated Rentcast API costs and savings
|
||||||
|
- **Usage Patterns**: Popular endpoints and request volumes
|
||||||
|
|
||||||
|
### Health Checks
|
||||||
|
|
||||||
|
```http
|
||||||
|
GET /health
|
||||||
|
```
|
||||||
|
|
||||||
|
Response includes:
|
||||||
|
- Database connectivity
|
||||||
|
- Cache backend status
|
||||||
|
- Active API keys count
|
||||||
|
- Recent error rates
|
||||||
|
- System uptime
|
||||||
|
|
||||||
|
### Metrics Endpoint
|
||||||
|
|
||||||
|
```http
|
||||||
|
GET /metrics
|
||||||
|
```
|
||||||
|
|
||||||
|
Provides detailed system metrics including:
|
||||||
|
- Request volumes and cache performance
|
||||||
|
- Per-endpoint statistics
|
||||||
|
- Cost analysis and savings
|
||||||
|
- System resource utilization
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### Production Deployment
|
||||||
|
|
||||||
|
1. **Use PostgreSQL**: Replace SQLite with PostgreSQL for production
|
||||||
|
2. **Enable Redis**: Use Redis for better cache performance
|
||||||
|
3. **Configure Logging**: Use structured JSON logging
|
||||||
|
4. **Set Up Monitoring**: Monitor metrics and health endpoints
|
||||||
|
5. **Use Reverse Proxy**: Nginx or Traefik for SSL termination
|
||||||
|
6. **Environment Variables**: Never commit secrets to code
|
||||||
|
|
||||||
|
## 📈 Performance Tips
|
||||||
|
|
||||||
|
### Optimization Strategies
|
||||||
|
|
||||||
|
1. **Cache Warming**: Pre-populate cache for popular endpoints
|
||||||
|
2. **Bulk Operations**: Use bulk endpoints when available
|
||||||
|
3. **Connection Pooling**: Configure appropriate database connection pools
|
||||||
|
4. **Response Compression**: Enable gzip compression for large responses
|
||||||
|
5. **CDN Integration**: Use CDN for static content and common API responses
|
||||||
|
|
||||||
|
### Monitoring Performance
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check cache hit ratios
|
||||||
|
rentcache stats --days 7
|
||||||
|
|
||||||
|
# Monitor response times
|
||||||
|
curl -s http://localhost:8000/metrics | jq '.avg_response_time_ms'
|
||||||
|
|
||||||
|
# Check system health
|
||||||
|
rentcache health
|
||||||
|
```
|
||||||
