Check them before you pick an idea. - Rank: The order the platform itself shows. Nothing is re-ranked here, so an entry with a smaller figure can sit above one with a bigger figure. - Heat: The platform's own heat score. It is an index, not a count of searches or plays: compare entries within this list, not across platforms. An entry the platform gives no score shows a dash. - Change: Places gained or lost since the reading before; the board is read once a day. `NEW` means the entry was not on the list then. - Updates: Read once a day. The time of the last reading is under the title, in UTC+8. Opening the page starts no reading. ## Other boards - [Weibo hot search](https://dataxapi.com/tools/hot-search/weibo/) - [Douyin hot search](https://dataxapi.com/tools/hot-search/douyin/) - [Bilibili hot search](https://dataxapi.com/tools/hot-search/bilibili/) - [Kuaishou hot list](https://dataxapi.com/tools/hot-search/kuaishou/) - [Zhihu hot list](https://dataxapi.com/tools/hot-search/zhihu/) - [Reddit trending searches](https://dataxapi.com/tools/hot-search/reddit/) - [X (Twitter) trending topics in the US](https://dataxapi.com/tools/hot-search/x/) ## Earlier days - [All 4 archived days](https://dataxapi.com/tools/hot-search/xiaohongshu/archive/) - [October 20, 2026](https://dataxapi.com/tools/hot-search/xiaohongshu/2026-10-20/) - [October 19, 2026](https://dataxapi.com/tools/hot-search/xiaohongshu/2026-10-19/) - [October 18, 2026](https://dataxapi.com/tools/hot-search/xiaohongshu/2026-10-18/) - [October 17, 2026](https://dataxapi.com/tools/hot-search/xiaohongshu/2026-10-17/) ## Questions ### How often is this page updated? The board is read once a day, and the time of the last reading is printed under the title. Opening the page does not trigger a new reading: the list is written into the page when it is rebuilt. ### Where do the figures come from? From Xiaohongshu (RedNote)'s own list. Nothing is estimated or adjusted: an entry the platform gives no figure has none here. ### Can I see an earlier day? Yes. Each day's final list is kept as a page of its own (a day counted in UTC+8); the days are listed under the board and in its archive. ### How much is this through the API? $0.0200 a call for about 20 entries. A failed call is not charged. ## By API - Endpoint: `GET /v1/xiaohongshu/trends/list` - Price: $0.0200 / call - [Xiaohongshu trends](https://dataxapi.com/apis/xiaohongshu/trends/list/) - [Run it in the Playground](https://dataxapi.com/console/playground/?capability=xiaohongshu.trends.list) ```bash curl "https://api.dataxapi.com/v1/xiaohongshu/trends/list" \ -H "Authorization: Bearer $DATAXAPI_API_KEY" ``` --- Catalog revision c48ce454ae6c4c65.
