Trend object
9 endpoints on 8 platforms return the Trend object with the same 4 fields, so code written for one platform reads the others unchanged. A call costs $0.0020 to $0.0200.
A Trend is one entry on a platform's hot list: a search term, a topic or a question, with its rank and the platform's own heat score where the platform gives them. Every platform's hot list comes back as this one object; where a platform has several lists, board picks one.
A trend has no ID on every platform: its name is what identifies it, and it can go as query to a search of the same platform to read what is behind it. On Zhihu an entry's id is its question's.
Fields
A field the platform cannot give is left out of the item and named in meta.unavailable. It is never filled with a guess or a zero.

Where each number comes from
The same field name does not always mean the same act on every platform. This table says which of the platform's own numbers goes into the field.
