Implementing Issue #6: Enable .env API Key Awareness

Todo List:

• Gather context (read CLAUDE.md and relevant files)
• Understand the current eodhistoricaldata_md.py structure
• Update env var name from EODHISTORICALDATA_API_TOKEN → EODHD_API_KEY
• Improve dotenv import style (from dotenv import load_dotenv)
• Add python-dotenv==1.1.0 to requirements.txt
• Commit changes
• Push to branch and create PR

Changes Made

data_engines_fundamentals/eodhistoricaldata_md.py

• Changed import dotenv → from dotenv import load_dotenv (cleaner, idiomatic style)
• Changed dotenv.load_dotenv() → load_dotenv()
• Updated env variable from EODHISTORICALDATA_API_TOKEN → EODHD_API_KEY to match the key defined in .env
• Updated warning messages to reference the correct env var name

requirements.txt

• Added python-dotenv==1.1.0 (was missing despite already being used in the code)

The API key is loaded once at initialization in __init__ and stored as self.api_token, which is then used in all API calls (get_eod_data, get_realtime_data, get_fundamentals, get_intraday_data, get_exchanges, get_dividends, get_technical_indicators). No other methods needed changes.
