## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| page_token | not declared | no | not declared | Page token for `popular`: pass back the previous response's `next_page_token` exactly as received to get the next 20 videos; leave it out to start at the first page. Tokens last 24 hours and each page is one call. |

## Response fields (items in `results`)

| field | meaning |
|---|---|
| id | The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms. |
| aid | The video's numeric av ID (popular); it names the same video as the BV ID in id. |
| url | Link to the record on the platform. |
| title | Title. null when the platform has no titles (for example text-only posts). |
| text | Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so). |
| duration_seconds | Duration in seconds. null for content that is not video or audio. |
| duration_sec | platform-native meaning |
| view_count | Views or plays. null means not disclosed, not 0. |
| like_count | Likes. null means the platform or this capability does not disclose it; it is not 0. |
| comment_count | Comments. null means not disclosed, not 0. |
| danmaku_count | Danmaku (on-screen comment) count. **A Bilibili-specific engagement signal; read it alongside comment_count.** |
| favorite_count | Favorites. |
| coin_count | Coins given. Coins are a paid form of approval on Bilibili and weigh more than likes. |
| share_count | Shares. null means not disclosed, not 0. |
| thumbnail_url | Thumbnail link, lower resolution than image_url. |
| posted_at | Publish time in ISO 8601, UTC (for example 2026-08-07T12:34:56+00:00). Non-standard strings from the platform are passed through as is, so parse defensively. null means the platform does not disclose it. |
| category | Category name in the platform's own taxonomy, not normalized across platforms. |
| author_name | Author's display name. |
| author_id | Author's unique ID on the platform. |
| author_url | Link to the author's profile on the platform. |
| author_avatar_url | Uploader avatar link (popular). |
| recommend_reason | The tag Bilibili puts on a Popular video, as shown (popular), for example for passing a million views or many shares; absent when there is none. |
| ip_location | Upload location (popular): the IP region Bilibili shows on the video page, a province or country. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
