FinViz Screener

Overview

Translate natural-language stock screening requests into FinViz screener filter codes, build the URL, and open it in Chrome. No API key required for public screener; FINVIZ Elite is auto-detected from $FINVIZ_API_KEY for enhanced functionality.

Key Features:

• Natural language → filter code mapping (Japanese + English)
• URL construction with view type and sort order selection
• Elite/Public auto-detection (environment variable or explicit flag)
• Chrome-first browser opening with OS-appropriate fallbacks
• Strict filter validation to prevent URL injection
