## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| url | not declared | yes | not declared | A Zhihu profile link (https://www.zhihu.com/people/<profile ID>) or the profile ID alone. Nicknames are not accepted; find the profile ID with `user_search` first. |
| page_token | not declared | no | not declared | Page token. Leave it out for the first page, then pass back the previous response's `next_page_token` exactly as received. 20 answers per page, newest first; 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. |
| type | Record type; values depend on the capability (for example video / image / text). |
| url | Link to the record on the platform. |
| question_id | ID of the question the answer belongs to (question_answers), the same as the requested question. |
| 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). |
| 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. |
| 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. |
| updated_at | When the answer was last edited (question_answers), ISO 8601 in UTC; the same as posted_at when never edited. |
| author_id | Author's unique ID on the platform. |
| author_name | Author's display name. |
| author_url | Link to the author's profile on the platform. |
| author_avatar_url | Author avatar URL; on comment results, the commenter's avatar. |
| author_bio | Author bio as written on Zhihu. |
| author_verification_label | Verification description of the author, such as a profession or institution. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
