Get the Weibo hot search brief (daily hot event digest), returning an AI-generated summary of the day's hot events. Each event contains a title, summary, hot search stats (e.g. "TOP1热搜×19", "热搜霸榜23小时") and source posts.
The brief is generated by Weibo AI search and is refreshed periodically; see slogan_info.dynamic_wenan for the update time
Returns about 20 hot events for the current day; this endpoint does not support pagination
The brief is a multi-level nested JSON string, callers need to deserialize it level by level
The brief is generated progressively by the AI; the server automatically retries when it hits an in-progress response. In rare cases an in-progress response is still returned, in which case analysis_result.chat_status_stage is not 0 and msg only holds the AI generation trace
