 # Changelog
 
+## 2025-11-02 - 3.3.0 - feat(stocks/CoinGeckoProvider)
+Add CoinGecko provider for cryptocurrency prices, export and tests, and update documentation
+
+- Implemented CoinGeckoProvider with rate limiting, coin-id resolution, and support for current, batch, historical and intraday price endpoints
+- Added unit/integration tests for CoinGecko: test/test.coingecko.node+bun+deno.ts
+- Exported CoinGeckoProvider from ts/stocks/index.ts
+- Updated README and readme.hints.md with CoinGecko usage, provider notes and examples
+- Added .claude/settings.local.json with webfetch and bash permissions required for testing and CI
+
+## 2025-11-01 - 3.2.2 - fix(handelsregister)
+Correct screenshot path handling in HandelsRegister and add local tool permissions
+
+- ts/classes.handelsregister.ts: Replace string concatenation for screenshot path with a template literal and explicit string assertion to ensure the path is formed correctly for page.screenshot() and avoid type issues.
+- Add .claude/settings.local.json: Introduce local Claude settings that grant specific tool permissions used during development and testing (bash commands, web fetches, pnpm build, tstest, etc.).
+
+## 2025-11-01 - 3.2.1 - fix(stocks/providers/provider.secedgar)
+Improve SEC EDGAR provider networking and error handling, update plugin path import, bump dev deps and add/refresh tests and lockfile
+
+- SEC EDGAR provider: switch from SmartRequest to native fetch for ticker list and company facts, add AbortController-based timeouts, handle gzip automatically, improve response validation and error messages, and keep CIK/ticker-list caching
+- Improve timeout and rate-limit handling in SecEdgarProvider (uses native fetch + explicit timeout clear), plus clearer logging on failures
+- Update ts/plugins import to use node:path for Node compatibility
+- Bump devDependencies: @git.zone/tsrun to ^1.6.2 and @git.zone/tstest to ^2.7.0; bump @push.rocks/smartrequest to ^4.3.4
+- Add and refresh comprehensive test files (node/bun/deno variants) for fundamentals, marketstack, secedgar and stockdata services
+- Add deno.lock (dependency lock) and a local .claude/settings.local.json for CI/permissions
+
 ## 2025-11-01 - 3.2.0 - feat(StockDataService)
 Add unified StockDataService and BaseProviderService with new stockdata interfaces, provider integrations, tests and README updates

 ## 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.
+The stocks module provides real-time stock price data and cryptocurrency prices through various provider implementations. Currently supports Yahoo Finance, Marketstack, and CoinGecko with an extensible architecture for additional providers.
 
 ### Architecture
 - **Provider Pattern**: Each stock data source implements the `IStockProvider` interface
@@ -31,11 +31,55 @@ const price = await stockService.getPrice({ ticker: 'AAPL' });
 console.log(`${price.ticker}: $${price.price}`);
 ```
 
+### CoinGecko Provider Notes
+- Cryptocurrency price provider supporting 13M+ tokens
+- Three main endpoints:
+  - `/simple/price` - Current prices with market data (batch supported)
+  - `/coins/{id}/market_chart` - Historical and intraday prices with OHLCV
+  - `/coins/list` - Complete coin list for ticker-to-ID mapping
+- **Rate Limiting**:
+  - Free tier: 5-15 calls/minute (no registration)
+  - Demo plan: 30 calls/minute, 10,000/month (free with registration)
+  - Custom rate limiter tracks requests per minute
+- **Ticker Resolution**:
+  - Accepts both ticker symbols (BTC, ETH) and CoinGecko IDs (bitcoin, ethereum)
+  - Lazy-loads coin list on first ticker resolution
+  - Caches coin mappings for 24 hours
+  - IDs with hyphens (wrapped-bitcoin) assumed to be CoinGecko IDs
+- **24/7 Markets**: Crypto markets always return `marketState: 'REGULAR'`
+- **Optional API Key**: Pass key to constructor for higher rate limits
+  - Demo plan: `x-cg-demo-api-key` header
+  - Paid plans: `x-cg-pro-api-key` header
+- **Data Granularity**:
+  - Historical: Daily data for date ranges
+  - Intraday: Hourly data only (1-90 days based on `days` param)
+  - Current: Real-time prices with 24h change and volume
+
+### Usage Example (Crypto)
+```typescript
+import { StockPriceService, CoinGeckoProvider } from '@fin.cx/opendata';
+
+const stockService = new StockPriceService({ ttl: 30000 });
+const coingeckoProvider = new CoinGeckoProvider(); // or new CoinGeckoProvider('api-key')
+stockService.register(coingeckoProvider);
+
+// Using ticker symbol
+const btc = await stockService.getPrice({ ticker: 'BTC' });
+console.log(`${btc.ticker}: $${btc.price}`);
+
+// Using CoinGecko ID
+const ethereum = await stockService.getPrice({ ticker: 'ethereum' });
+
+// Batch fetch
+const cryptos = await stockService.getPrices({ tickers: ['BTC', 'ETH', 'USDT'] });
+```
+
 ### 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
+- CoinGecko tests may take longer due to rate limiting (wait between requests)
