Weibo Trending returns the current hot search list, Weibo's ranking of what people are searching and talking about, and takes no parameters. Each entry carries its `rank`, the `title` of the topic, the `category` Weibo files it under, the heat figure in `hot_value`, the badge in `label`, the `is_hot` and `is_new` flags and a link. Newsrooms, PR teams and brand marketers read it to see what Weibo users are discussing, catch a topic that involves them early, and decide which trends are worth joining.

Read the list on a schedule and keep every snapshot with its time, since what matters is how fast an entry climbs and how long it stays. `category` uses Weibo's own taxonomy, so map it before you put this list next to trending lists from other platforms, and treat `hot_value` as Weibo's internal measure rather than a count of searches or posts.

## Response example

Real response to the example request above, captured 2026-09-26T08:56:04Z. `results` and `count` are real with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2 of 20. `id`, `billing` and `quota` differ on every call, so only their shape is shown.

## FAQ

### What do `label`, `is_hot` and `is_new` mean?

`label` is the badge Weibo shows beside an entry, such as new, hot or exploding. `is_hot` marks entries flagged as hot, and `is_new` marks entries that have just entered the list, which makes it the field to watch when you want early alerts about emerging topics.

### Can I compare `hot_value` between two days?

Not directly. The value is Weibo's own metric and is only meant for comparing entries within one list. To follow a topic across time, read the list on a schedule and record each entry's `rank` with the time of the read; rank positions line up from one snapshot to the next.

### How do I see the posts behind a trending topic?

Use the entry's `title` as the keyword for the Weibo Search capability, which returns public posts with their authors and repost, comment and like counts. The entry's `url` opens the topic on Weibo when you want to look at it yourself.
