The videos trending in one region, from the official Data API v3 (videos.list with chart=mostPopular, 1 quota unit, 1 credit) — up to 50, in chart order, with exact view, like and comment counts. `region` is REQUIRED on purpose: trending does not exist without a region, and a silent default would publish one country's chart as if it were the world's. There is no author: the list belongs to a region, not to an account. has_more is null, never false, and no category name is returned.

The videos trending in one region, from the official Data API v3 (videos.list with chart=mostPopular, 1 quota unit) -- up to 50, in chart order, with exact view, like and comment counts. The region parameter is REQUIRED on purpose: trending does not exist without a region, and a silent default would publish one country's chart as if it were the world's. There is no author -- the list belongs to a region, not to an account, so the twelve author fields are null by decision. has_more is null, never false. The category is not returned: snippet carries a numeric categoryId whose meaning needs another call we do not make, and serving the raw number would serve a code the client cannot resolve.
