How It Works

Fetches posts from Reddit's public JSON API (no auth required)
Extracts ticker symbols using regex ($TSLA, TSLA, etc.)
Analyzes sentiment using bullish/bearish word matching
Returns structured JSON with mentions, scores, and sentiment

Limitations

Reddit rate limits (~60 requests/minute without auth)
Simple word-based sentiment (no ML)
Only scans post titles and selftext (not comments)
Ticker extraction may have false positives
