🎯 Refactor API to Use httpx
Introduces a `language` parameter to functions for fetching metadata and securities data, allowing data to be retrieved in either English or Thai. Updates the service layer to propagate the `language` parameter and include default values. Adds validation for acceptable language inputs and modifies URLs to fetch language-specific data files.
🛠️ Technical Implementation:
• Integrated Thai Securities Data API as secondary data source for company metadata
• Added full multilingual support (English/Thai) for Stock class initialization
• Implemented missing Stock.search() and Stock.list_symbol() class methods
• Enhanced Stock class with SafeProperty descriptor for clean attribute access
• Added comprehensive service layer abstraction for both data sources
• Updated all modules with proper docstrings and type hints
📁 Files Added/Modified:
• thaifin/stock.py - Enhanced with dual data sources and language support
• thaifin/sources/thai_securities_data/ - Complete new API integration module
• thaifin/sources/finnomena/ - Enhanced service layer and improved documentation
• .github/copilot-instructions.md - Updated with dual data source architecture and uv usage
✅ Benefits:
• Users can now access Thai and English company names seamlessly
• Fuzzy search functionality for finding companies by name
• Complete list of stock symbols via Stock.list_symbol()
• Robust error handling and caching for both data sources
• Clean separation of financial data (Finnomena) and metadata (Thai Securities Data)
🧪 Tested:
• Stock creation with language parameter: Stock('PTT', language='th')
• Search functionality: Stock.search('จัสมิน', limit=5)
• Symbol listing: Stock.list_symbol() returns 922 symbols
• All tests pass with uv run python execution
