# Douyin trend-index live hot topics API

The Douyin trend-index live hot topics API returns the live topic board or the fastest-rising topic board of Douyin's index tool, about 30 entries each: place, name, topic index, number of related videos, their plays and a category. The topic index is the platform's score of heat, not a count of searches. One call costs 2 credits ($0.004 to $0.0067 depending on the pack); failed calls are free. Last tested 2026-10-17.

## Paging and failures

- One call returns the first page only, up to 50 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](https://socialtoai.com/docs/credits-and-billing.md#rate-limits)
- A failed call costs 0 credits and is never retried on its own. [Error codes](https://socialtoai.com/docs/api/errors.md)

## 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.

**Can I get the next page?**

No. On Douyin this interface gives its first page only (up to 50 items): the response carries no cursor, and page.has_more is always false.
