## Response fields (items in `results`)

| field | meaning |
|---|---|
| title | Title. null when the platform has no titles (for example text-only posts). |
| url | Link to the record on the platform. |
| 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). |
| cover_image_url | platform-native meaning |
| discuss_count | Number of discussions under the topic (topic_search). |
| read_count | Number of reads of the topic (topic_search). |
| next_page_token | Page token (user_search, user_posts, topic_search, user_post_search): pass it back unchanged as page_token for the next page. Every row of a page carries the same value, which also appears at the top level of the response; absent on the last page. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
