Notes

• Login-gated pages: Songs detail, Videos inspiration, Creator highlights — these require login. Fall back to home page + hashtag data if login pages return empty.
• Emoji indicator: 🆕 marks hashtags newly entering Top 100, ↑ marks rising trends
• No browser needed: web_fetch works fine on TikTok Creative Center (unlike the main TikTok.com which requires JS rendering)
• All regions default: The pages above use global/"All regions" filter. For China-specific Douyin data, this skill has limited coverage — Douyin blocks most automated access.
• Time: Always record the fetch timestamp — trends change daily
