## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| keyword | not declared | yes | not declared | Specifies the primary search string according to the requested Amazon action. In search, pass the product search terms. In bestsellers, pass a full Amazon bestsellers category URL or a category short name used to build the path. In sellers, pass a product or seller page URL; raw search terms generate a product search page rather than looking up a seller ID directly. |
| lang | enum: ar / bn / cs / da / de / en / es / fr / he / hi / ja / kn / ko / ml / mrta / nl / pl / pt / sv / ta / te / tr / zhcn / zhtw | no | not declared | Specifies the page language for supported Amazon endpoints using valid codes such as en or ja. Use zhcn for Simplified Chinese and zhtw for Traditional Chinese instead of a generic zh code. Requests accept only the language codes listed for the action, and selecting a language alters the rendered content rather than changing the target country store. |
| 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. |
| url | Link to the record on the platform. |
| name | Name of the object itself, for account, product and business capabilities. |
| rank | platform-native meaning |
| price | Price as a number without a currency symbol; see currency. |
| rating | Rating. **The scale varies by platform**: rating_scale on the same row gives the maximum (usually 5; Booking, Douban, iQIYI and NAVER use 10). Convert with rating_scale before comparing across platforms, or the comparison can come out backwards. |
| rating_scale | Maximum of rating in the same row: 5 for five-star scales, 10 for ten-point scales. Present only when the row has a rating. |
| review_count | Number of reviews, for product and business capabilities. null means not disclosed, not 0. |
| offer_count | platform-native meaning |
| category | Category name in the platform's own taxonomy, not normalized across platforms. |
| image_url | Image link. Capabilities with several images may return an image_urls array. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |

## Response example
