  .then(r => r.json())

• Auto failover — tries Kitco first, falls back to Macrotrends, then GoldAPI
• 20-second cache — reduces upstream calls, stays under rate limits
• No API key required — completely free to use
• CORS enabled — call it from any domain or tool
• No rate limit — the cache handles bursts automatically

# Python example
import requests
r = requests.get('https://silverstackcalculator.qd.je/api/silver-price')
data = r.json()
print(f"Silver: ${data['bid']} (bid) / ${data['ask']} (ask)")
