Prices are realistic reference figures. Base prices refreshed by rare-earths-price-bot-005.js (H1 fix: expanded to 68+ items with EXACT "name" key alignment from this page\'s METALS/GASES data for rare-earth/battery categories + key base). Live tick is demo on top. Run the v5 bot (or cron) to get fresh data into rare-earths-prices-005.json. (Original 001 uses old bot/json for comparison.) Units vary by market convention: structural steel /lb, base metals /lb, precious metals per troy ounce (ozt), rare earths and battery materials /kg, some specialty items /g. Always confirm against your supplier's live quote.
