Weibo Trending API

Q: 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.

Q: 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.

Pull Weibo's current hot search list, up to 200 entries. Each entry has rank, topic, category, heat value, badge and hot or new flags. hot_value is Weibo's own measure and compares only within the list. No history is kept, so store snapshots yourself.

Send POST https://api.everyinfra.com/api/v1/social with platform set to weibo and action set to trending. Price $0.56 per 1,000 requests ($0.000556 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

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.

AI prompt

Please help me write a data collection script with the EveryInfra Weibo Trending endpoint (weibo/trending).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to weibo and action to trending, and put the parameters inside params.
- No required parameters.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 200. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 20)
- Returns a list of records. Main fields of each record: rank, title, category, hot_value, label, is_hot, is_new, url.
- Example request body:
{
  "platform": "weibo",
  "action": "trending",
  "params": {}
}
- Price: $0.56 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

`category`	Category name in the platform's own taxonomy, not normalized across platforms.
`hot_value`	Keeps the platform's own meaning
`label`	Keeps the platform's own meaning
`is_hot`	Keeps the platform's own meaning
`is_new`	Keeps the platform's own meaning
`url`	Link to the record on the platform.

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.
