## 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.
