401	Invalid or expired token

Usage Tips

Always use `$PREFIX/bin/curl` - System curl is broken on Android
For large pages, use /chrome/scrape to extract specific elements instead of full HTML
For SPAs, add waitForSelector to ensure content is loaded
Save screenshots to /tmp/ for temporary files
Rate limits: Free tier has limited concurrent sessions, add small delays between requests
