“What is trending right now?” is the most common question an agent gets about social media, and the answer lives in a dozen different hot lists, each on a platform that does not want to be read. Through AgentKey your agent reads all of them the same way — find_tools, describe_tool, execute_tool — and can start from a single cross-platform ranking before drilling into one network.

​

FAQ

Live lists — Weibo hot search, Douyin hot search, X trends, Zhihu hot list, Bilibili popular — are read from the platform at request time. The daily rankings (Douyin hot works and like-surge, Xiaohongshu hot notes, WeChat viral articles) describe the previous day and are refreshed once a day.
Partly. The cross-platform keyword search covers a date range of up to 30 days, Weibo has a hot ranking timeline, and several daily rankings accept a date. Live lists have no history; capture them on a schedule if you need one.
X trends take a country, Douyin has a city hot list, and TikTok’s search accepts a region. Other lists return what the platform serves for its default region.
