A Cloudflare Worker that fetches, processes, and caches consumer price data from the Bureau of Labor Statistics (BLS) API.

• Processes data for all US regions (national, northeast, midwest, south, west)
• Runs on a daily schedule via Cloudflare Workers
• Supports manual updates via authenticated API endpoint
• Stores processed data in Cloudflare R2 buckets

• Node.js (LTS version recommended)
• Yarn package manager
• Cloudflare account with Workers and R2 access
• BLS API key (register at https://www.bls.gov/developers/)
