## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| url | not declared | yes | not declared | The target URL required by YouTube actions. Use full channel URLs for profile and user_posts, or specific watch?v= and share links for video, comments, and transcript. Channel metadata is derived from published content, and comments does not return channel community board posts. |
| since | not declared | no | not declared | The lower date bound for filtering channel videos, Shorts, or comments. It applies to those lists only. |
| sort | enum: newest / popular | no | not declared | The sort order applied across YouTube actions. For search, accepted values are relevance, newest, most_viewed, and top_rated. For channel videos and Shorts, accepted values are newest, oldest, and popular. For comments, accepted values are newest and popular. Specifying this parameter on a single-video query does not filter that video's content. |
| limit | integer (1–100) | no | 20 | The most rows to return in this call, an integer from 1 to 100. 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. |
| 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. |
| like_count | Likes. null means the platform or this capability does not disclose it; it is not 0. |
| reply_count | Replies, usually replies to a comment. null means not disclosed. |
| 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. |
| is_reply | platform-native meaning |
| reply_to_id | platform-native meaning |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
