- 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
Reddit Post (normalized)
Normalized Reddit post. Provider-private fields MUST NOT appear. Metric names are frozen (upvotes/downvotes/comments — 升/降票/评论). `title` is the platform extension field (the post headline — text carries the selftext body); `url` is the post link. The id is the t3 base36 id without prefix. author is nullable: posts by deleted/suspended accounts ship no resolvable author (a present-but-incomplete author block still fails).
