FAQ

Is there pagination?
No page parameter. Beyond the limit, vary the keyword or add qualifiers.
Do Chinese keywords work on TikTok?
They return results, but relevance drops sharply. Use English for TikTok.
Can one key cover every platform?
Keys belong to groups: overseas platforms use the overseas group, Douyin/Xiaohongshu the domestic group. One account can hold both.
Search posts vs search creators?
Posts gives content; creators gives accounts with follower counts and bios — follow up with profile and creator-posts endpoints.
