## Response fields (items in `results`)

| field | meaning |
|---|---|
| id | 该记录在原平台上的唯一标识。仅在同一平台内唯一，跨平台可能重复。 |
| text | 正文内容，已去除 HTML 标签，全文返回、不截断（个别平台的列表结果本身只有摘要，以该平台的字段说明为准）。 |
| author_name | 作者昵称（显示名）。 |
| author_username | 作者用户名（@handle），通常可用于拼 URL。 |
| depth | 评论层级：0 是顶层评论（一级），1 是对顶层评论的回复（二级），2 是对回复的再回复（三级）。深度行的 id 与其父评论组相同，重建评论树请用 depth + reply_to_id。主来源不可用时，备用来源只返回顶层评论：每一行的 depth 都是 0，没有回复行。 |
| reply_to_id | 被回复评论的 ID（depth>=1 才有；depth=0 恒为空）。回复行的 id 会复用父评论组 ID，要区分父子请以本字段为准。 |
| comment_url | 该条评论的永久链接；深度行的链接带 reply_comment_id 参数指向被回复的评论。 |
| author_id | 评论作者的数字用户 ID（稳定标识，可用于跨请求去重）。 |
| author_url | 评论作者的主页链接。 |
| like_count | 点赞数。null 表示该平台或该接口不公开此数据，不等于 0。 |
| reply_count | 回复数，通常用于评论的子回复。null 表示不公开。 |
| posted_at | 发布时间，ISO 8601 格式、UTC 时区（如 2026-08-07T12:34:56+00:00）。平台只给非标准字符串时原样透传，解析前建议做容错。null 表示平台未公开。 |
| platform | 数据来源平台标识，与请求里的 platform 一致（如 xiaohongshu、tiktok）。 |

curl -X POST 'https://api.everyinfra.com/api/v1/social' \

    "https://api.everyinfra.com/api/v1/social",
    headers={"Authorization": f"Bearer {os.environ['EVERYINFRA_API_KEY']}"},
    json={
        "platform": "facebook",
        "action": "comments",
        "params": {
            "url": "https://www.facebook.com/nasa",

print(response.status_code)
print(response.json())
```

## Response example

Real response to the example request above, captured 2026-10-24T18:28:34Z. `results` and `count` are real with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2 of 16. `id`, `billing` and `quota` differ on every call, so only their shape is shown.
