# Douyin trend-index creator follower profile API

The Douyin trend-index creator follower profile API returns who follows a Douyin account from the platform's own index tool, by the account's numeric ID: the share of each segment by gender, age, province, city, city tier, phone brand and interest. Not limited to marketplace creators; shares only, no head counts. One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Call it over HTTP or from your AI client over MCP. Last tested 2026-10-17.

## FAQ

**Do I need a Douyin account or Douyin's own API access?**

No. You only need a SocialToAI key. The call returns content and account information publicly visible on Douyin; you never sign in to Douyin or apply for anything there.

**What does “Preview” mean here?**

Preview: this interface is not marked stable yet, so its parameters and fields may still change. It is charged like any other call, and a failed call is not charged.
