## Response fields (items in `results`)

| field | meaning |
|---|---|
| name | 名称。用于账号/商品/商家类能力，指该对象本身的名字。 |
| slug | 该条目的 URL 短名。 |
| url | 该记录在原平台上的可访问链接。 |
| vendor_name | 厂商名称。 |
| vendor_slug | 厂商 URL 短名。 |
| category | 分类名称，取值为原平台的分类体系，未做跨平台归一。 |
| category_slug | 分类的 URL 短名。 |
| rating | 评分。**分制随平台而异**，同一行的 `rating_scale` 给出该平台满分 (多数是 5，Booking/豆瓣/爱奇艺/NAVER 是 10)。跨平台比较前必须先按 rating_scale 换算。直接比数字会得出反的结论。 |
| rating_scale | 上一列 `rating` 的满分。5 表示五星制、10 表示十分制。只在该行有 rating 时出现。 |
| review_count | 评价条数，用于商品/商家类能力。null 表示不公开，不等于 0。 |
| rank | 在所属分类里的排名。 |
| page | 所在页码。 |
| image_url | 图片链接。多图能力可能返回 image_urls 数组。 |
| platform | 数据来源平台标识，与请求里的 platform 一致（如 xiaohongshu、tiktok）。 |
| description | 简介或描述，通常比 text 短。 |
| rating_out_of_ten | 10 分制评分。**与 aggregate_rating 量纲不同，别混着比。** |
| entry_level_price | 入门档价格。 |
| is_sponsored | 是否为付费推广位。**推广位排在前面不代表评分更高。** |
| awards | 获得的 G2 奖项（如 Leader、High Performer）。 |

## Response example

Real response to the example request above, captured 2026-09-26T08:56:04Z. `results` and `count` are real with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2 of 10. `id`, `billing` and `quota` differ on every call, so only their shape is shown.
