## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| asins | not declared | yes | not declared | The ASINs for `rank_overview` (1 to 20) or `keyword_intersections` (2 to 10), as an array or a comma-separated string; each is 10 uppercase letters or digits, such as `B0C2JXSHSK`. Only the US marketplace (amazon.com) is covered. On `rank_overview` each ASIN gets its own row and one without keyword data is left out; on `keyword_intersections` each row is a keyword all of the products rank for. Any other count is rejected before the call runs. |
| 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 are accepted and capped at the maximum. |

## Response fields (items in `results`)

| field | meaning |
|---|---|
| keyword | A search keyword: one the product ranks for on ranked_keywords, one you asked about on bulk_search_volume. |
| search_volume | Estimated monthly searches for the keyword on Amazon US (ranked_keywords, bulk_search_volume). It is demand for the whole keyword, not traffic to any product; 0 means too small to measure, and on bulk_search_volume a keyword with too few searches gets no row. |
| ranked_at | When the position was seen, ISO 8601 in UTC (ranked_keywords). It differs by keyword and can be weeks old. |
| rankings | platform-native meaning |
| total_keywords | How many keywords the product ranks for in total (ranked_keywords), the same on every row; one call returns at most 100. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
