Questions.
Short answers.
Everything on DouyinDo 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.
