1 个已发布端点
GET /v1/youtube/posts/{id}

契约摘要（英文）: Get a normalized YouTube video (capability youtube.post)

标准化响应实体: youtube/post

使用场景

支撑需要原始内容与互动数据的审核、研究与监测流程。
以稳定的标准化 JSON 归档 {{platform}} 内容，告别脆弱的网页抓取。

返回字段

YouTube Video Post (normalized)

Normalized YouTube video. Provider-private fields MUST NOT appear. Metric names are frozen (views/likes/comments — 观播放/赞/评); hidden counts normalize to 0. `title` is the platform extension field (the video headline — text carries the description). author and created_at are nullable: search/list cards may omit the channel block and the web surface sometimes ships only relative publish-time text ("2 weeks ago" — lossy, never fabricated into an instant; a present-but-unparsable timestamp still fails).
