## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| keyword | not declared | yes | not declared | Specifies the search query for distinct platform endpoints. For search, it searches public posts; for ads, it accepts ad keywords or direct Ad Library and Page URLs; for marketplace, it accepts item search terms or complete Marketplace search URLs. Each action queries a different dataset rather than returning the same results under different field names. |
| content_type | enum: latest / most_popular | no | not declared | Sorts results for the search action using allowed values latest for newer posts or most_popular for popular posts. Despite its name, content_type acts as a sorting dimension and does not filter by media format, such as images or videos. |
| since | not declared | no | not declared | Filters post publication dates for the search action from this start date, recommended in YYYY-MM-DD format. Combined with until, it forms the query date range; it does not filter ad run times or comment creation times. |
| until | not declared | no | not declared | Filters post publication dates for the search action up to this end date, recommended in YYYY-MM-DD format. Combined with since, it forms the query date range; it does not control ad expiration dates. |
| limit | integer (1–200) | no | 10 | The most rows to return in this call, an integer from 1 to 200. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. |

## 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. |
| 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). |
| author_name | Author's display name. |
| author_username | Author's username (@handle), usually usable in URLs. |
| author_id | Numeric user id of the comment author (stable identifier for cross-request deduplication). |
| author_url | Profile link of the comment author. |
| author_avatar_url | platform-native meaning |
| media | platform-native meaning |
| reactions | platform-native meaning |
| view_count | Views or plays. null means not disclosed, not 0. |
| link | platform-native meaning |
| group_name | platform-native meaning |
| is_paid_partnership | platform-native meaning |
| 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. |
| share_count | Shares. 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. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
