Douyin trend-index keyword hot videos API

Only on Douyin.

The Douyin trend-index keyword hot videos API returns the roughly 20 high-index videos Douyin's index tool puts forward for a keyword: caption, link, author's display name, likes, video index and category. One page only; the author's ID and the publication time are not given, the video endpoint has them. 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.

Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format

What to expect.

One call returns the first page only, up to 20 items, with no cursor, for 2 credits.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits.

1 call per second per key, 5 after a purchase; going over is not charged. Rate limits

A failed call costs 0 credits and is never retried on its own. Error codes

Once connected over MCP, these questions use it.

Questions.
Short answers.

Everything on Douyin
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.
Can I get the next page?
No. On Douyin this interface gives its first page only (up to 20 items): the response carries no cursor, and page.has_more is always false.
