/v1/call/douyin.kol_keywordsPreviewDouyin KOL content keywords API (Xingtu)
Only on Douyin.
The Douyin KOL content keywords API (Xingtu) returns the words a Douyin creator's recent videos keep coming back to, by Xingtu creator ID: about twenty, each with how many times the marketplace counted it. It shows what the creator has been talking about lately; the counts are in single digits, so the data is thin. One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Last tested 2026-10-17.
