+# OpenData Project Hints
+
+## Stocks Module
+
+### Overview
+The stocks module provides real-time stock price data through various provider implementations. Currently supports Yahoo Finance with an extensible architecture for additional providers.
+
+### Architecture
+- **Provider Pattern**: Each stock data source implements the `IStockProvider` interface
+- **Service Registry**: `StockPriceService` manages providers with priority-based selection
+- **Caching**: Built-in cache with configurable TTL to reduce API calls
+- **Fallback Logic**: Automatic failover between providers if one fails
+
+### Yahoo Finance Provider Notes
+- Uses public API endpoints (no authentication required)
+- Two main endpoints:
+  - `/v8/finance/chart/{ticker}` - Single ticker with full data
+  - `/v8/finance/spark?symbols={tickers}` - Multiple tickers with basic data
+- Response data is in `response.body` when using smartrequest
+- Requires User-Agent header to avoid rate limiting
+
+### Usage Example
+```typescript
+import { StockPriceService, YahooFinanceProvider } from '@fin.cx/opendata';
+
+const stockService = new StockPriceService({ ttl: 60000 });
+const yahooProvider = new YahooFinanceProvider();
+stockService.register(yahooProvider);
+
+const price = await stockService.getPrice({ ticker: 'AAPL' });
+console.log(`${price.ticker}: $${price.price}`);
+```
+
+### Testing
+- Tests use real API calls (be mindful of rate limits)
+- Mock invalid ticker 'INVALID_TICKER_XYZ' for error testing
+- Clear cache between tests to ensure fresh data
+- The spark endpoint may return fewer results than requested
+
+### Future Providers
+To add a new provider:
+1. Create `ts/stocks/providers/provider.{name}.ts`
+2. Implement the `IStockProvider` interface
+3. Register with `StockPriceService`
+4. No changes needed to existing code

+
+// Get multiple prices at once
+const prices = await stockService.getPrices({ 
+  tickers: ['AAPL', 'MSFT', 'GOOGL', 'BTC-USD', 'ETH-USD'] 
+});
+
+// Market indices, crypto, forex, commodities - all supported!
+const marketData = await stockService.getPrices({

+const details = await openData.handelsregister.getSpecificCompany({
+  court: "Munich",
+  type: "HRB",
+  number: "6684"
+});

-### Updating Business Data
-
-The `GermanBusinessData` class handles the specifics of updating and maintaining the data.
-
-#### Updating German Business Data
-
-```typescript
-import { OpenData } from '@fin.cx/opendata';
-
-const updateGermanBusinessData = async (openData: OpenData) => {
-  await openData.germanBusinesses.update();
-  console.log('German business data updated.');
-};
-
-startOpenDataInstance()
-  .then((openData) => {
-    // Use the instance
-    return updateGermanBusinessData(openData);
-  })
-  .catch(console.error);
-```
-
-This function downloads the latest data from the German business data source, processes it, and updates the local database.
-
-### Detailed Class Structures and Methods
-
-#### OpenData Class
-
-The `OpenData` class is the main entry point.
-
-```typescript
-import { OpenData } from '@fin.cx/opendata';
-
-class OpenData {
-  db: plugins.smartdata.SmartdataDb;
-  germanBusinesses: GermanBusinessData;
-
-  private serviceQenv = new plugins.qenv.Qenv(paths.packageDir, paths.nogitDir);
-
-  public CBusinessRecord = plugins.smartdata.setDefaultManagerForDoc(this, BusinessRecord);
-
-  public async start() {
-    // Initialize smart data DB
-    this.db = new plugins.smartdata.SmartdataDb({
-      mongoDbUrl: await this.serviceQenv.getEnvVarOnDemand('MONGODB_URL'),
-      mongoDbName: await this.serviceQenv.getEnvVarOnDemand('MONGODB_NAME'),
-      mongoDbUser: await this.serviceQenv.getEnvVarOnDemand('MONGODB_USER'),

-    this.germanBusinesses = new GermanBusinessData(this);
-    await this.germanBusinesses.start();
-  }
-
-  public async stop() {
-    // Clean up resources if necessary
-  }
+// Downloaded files include:

+# Stock Prices Module Implementation Plan
+
+Command to reread guidelines: Read /home/philkunz/.claude/CLAUDE.md
+
+## Overview
+Implementation of a stocks module for fetching current stock prices using various APIs. The architecture will support multiple providers, but we'll start with implementing only Yahoo Finance API. The design will make it easy to add additional providers (Alpha Vantage, IEX Cloud, etc.) in the future without changing the core architecture.
+
+## Phase 1: Yahoo Finance Implementation
+
+### 1.1 Research & Documentation
+- [ ] Research Yahoo Finance API endpoints (no official API, using public endpoints)
+- [ ] Document available data fields and formats
+- [ ] Identify rate limits and restrictions
+- [ ] Test endpoints manually with curl
+
+### 1.2 Module Structure
+```
+ts/
+├── index.ts                    # Main exports
+├── plugins.ts                  # External dependencies
+└── stocks/
+    ├── index.ts                # Stocks module exports
+    ├── classes.stockservice.ts # Main StockPriceService class
+    ├── interfaces/
+    │   ├── stockprice.ts      # IStockPrice interface
+    │   └── provider.ts        # IStockProvider interface (for all providers)
+    └── providers/
+        ├── provider.yahoo.ts   # Yahoo Finance implementation
+        └── (future: provider.alphavantage.ts, provider.iex.ts, etc.)
+```
+
+### 1.3 Core Interfaces
+```typescript
+// IStockPrice - Standardized stock price data
+interface IStockPrice {
+  ticker: string;
+  price: number;
+  currency: string;
+  change: number;
+  changePercent: number;
+  timestamp: Date;
+  provider: string;
+}
+
+// IStockProvider - Provider implementation contract
+interface IStockProvider {
+  name: string;
+  fetchPrice(ticker: string): Promise<IStockPrice>;
+  fetchPrices(tickers: string[]): Promise<IStockPrice[]>;
+  isAvailable(): Promise<boolean>;
+}
+```
+
+### 1.4 Yahoo Finance Provider Implementation
+- [ ] Create YahooFinanceProvider class
+- [ ] Implement HTTP requests to Yahoo Finance endpoints
+- [ ] Parse response data into IStockPrice format
+- [ ] Handle errors and edge cases
+- [ ] Add request throttling/rate limiting
+
+### 1.5 Main Service Class
+- [ ] Create StockPriceService class with provider registry
+- [ ] Implement provider interface for pluggable providers
+- [ ] Register Yahoo provider (with ability to add more later)
+- [ ] Add method for single ticker lookup
+- [ ] Add method for batch ticker lookup
+- [ ] Implement error handling with graceful degradation
+- [ ] Design fallback mechanism (ready for multiple providers)
+
+## Phase 2: Core Features
+
+### 2.1 Service Architecture  
+- [ ] Create provider registry pattern for managing multiple providers
+- [ ] Implement provider priority and selection logic
+- [ ] Design provider health check interface
+- [ ] Create provider configuration system
+- [ ] Implement provider discovery mechanism
+- [ ] Add provider capability querying (which tickers/markets supported)
+
+## Phase 3: Advanced Features
+
+### 3.1 Caching System
+- [ ] Design cache interface
+- [ ] Implement in-memory cache with TTL
+- [ ] Add cache invalidation logic
+- [ ] Make cache configurable per ticker
+
+### 3.2 Configuration
+- [ ] Provider configuration (timeout, retry settings)
+- [ ] Cache configuration (TTL, max entries)
+- [ ] Request timeout configuration
+- [ ] Error handling configuration
+
+### 3.3 Error Handling
+- [ ] Define custom error types
+- [ ] Implement retry logic with exponential backoff
+- [ ] Add circuit breaker pattern for failing providers
+- [ ] Comprehensive error logging
+
+## Phase 4: Testing
+
+### 4.1 Unit Tests
+- [ ] Test each provider independently
+- [ ] Mock HTTP requests for predictable testing
+- [ ] Test error scenarios
+- [ ] Test data transformation logic
+
+### 4.2 Integration Tests
+- [ ] Test with real API calls (rate limit aware)
+- [ ] Test provider fallback scenarios
+- [ ] Test batch operations
+- [ ] Test cache behavior
+
+### 4.3 Performance Tests
+- [ ] Measure response times
+- [ ] Test concurrent request handling
+- [ ] Validate cache effectiveness
+
+## Implementation Order
+
+1. **Week 1: Yahoo Finance Provider**
+   - Research and test Yahoo endpoints
+   - Implement basic provider and service
+   - Create core interfaces
+   - Basic error handling
+
+2. **Week 2: Service Architecture**
+   - Create extensible provider system
+   - Implement provider interface
+   - Add provider registration
+
+3. **Week 3: Advanced Features**
+   - Implement caching system
+   - Add configuration management
+   - Enhance error handling
+
+4. **Week 4: Testing & Documentation**
+   - Write comprehensive tests
+   - Create usage documentation
+   - Performance optimization
+
+## Dependencies
+
+### Required
+- `@push.rocks/smartrequest` - HTTP requests
+- `@push.rocks/smartpromise` - Promise utilities
+- `@push.rocks/smartlog` - Logging
+
+### Development
+- `@git.zone/tstest` - Testing framework
+- `@git.zone/tsrun` - TypeScript execution
+
+## API Endpoints Research
+
+### Yahoo Finance
+- Base URL: `https://query1.finance.yahoo.com/v8/finance/chart/{ticker}`
+- No authentication required
+- Returns JSON with price data
+- Rate limits unknown (need to test)
+- Alternative endpoints to explore:
+  - `/v7/finance/quote` - Simplified quote data
+  - `/v10/finance/quoteSummary` - Detailed company data
+
+## Success Criteria
+
+1. Can fetch current stock prices for any valid ticker
+2. Extensible architecture for future providers
+3. Response time < 1 second for cached data
+4. Response time < 3 seconds for fresh data
+5. Proper error handling and recovery
+6. Comprehensive test coverage (>80%)
+
+## Notes
+
+- Yahoo Finance provides free stock data without authentication
+- **Architecture designed for multiple providers**: While only implementing Yahoo Finance initially, all interfaces, classes, and patterns are designed to support multiple stock data providers
+- The provider registry pattern allows adding new providers without modifying existing code
+- Each provider implements the same IStockProvider interface for consistency
+- Future providers can be added by simply creating a new provider class and registering it
+- Implement proper TypeScript types for all data structures
+- Follow the project's coding standards (prefix interfaces with 'I')
+- Use plugins.ts for all external dependencies
+- Keep filenames lowercase
+- Write tests using @git.zone/tstest with smartexpect syntax
+- Focus on clean, extensible architecture for future growth
+
+## Future Provider Addition Example
+
+When ready to add a new provider (e.g., Alpha Vantage), the process will be:
+1. Create `ts/stocks/providers/provider.alphavantage.ts`
+2. Implement the `IStockProvider` interface
+3. Register the provider in the StockPriceService
+4. No changes needed to existing code or interfaces
