## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| app_id | not declared | yes | not declared | Apple's numeric app ID, such as `324684580`, or the app's apps.apple.com link, from which the digits after id are taken. A Bundle ID such as com.example.app is not accepted and is rejected before the call runs. |
| country | not declared | no | not declared | Storefront for `keywords_for_app`. Only the US store is covered: leave it out or pass us; any other country 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 the app ranks for (keywords_for_app). |
| search_volume | Search volume of the keyword in the US App Store (keywords_for_app), demand for the whole keyword rather than traffic to this app. |
| search_rank | The app's position in that keyword's App Store search results, from 1 (keywords_for_app). |
| search_result_count | How many apps the store returns for the keyword (keywords_for_app). |
| ranked_at | When the rank and search volume for this keyword were last updated, ISO 8601 (keywords_for_app). The data refreshes weekly to monthly, not in real time. |
| app_id | platform-native meaning |
| title | Title. null when the platform has no titles (for example text-only posts). |
| url | Link to the record on the platform. |
| icon_url | platform-native meaning |
| developer | platform-native meaning |
| 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. |
| rating_count | Number of people who rated. null means not disclosed, not 0. |
| is_free | Whether the app is free to download (keywords_for_app). |
| price | Price as a number without a currency symbol; see currency. |
| currency | Currency code of the price (for example CNY, USD). If price is present but currency is null, do not assume a currency. |
| total_keywords | How many keywords the app ranks for in total (keywords_for_app), the same on every row; limit only sets how many of them this call returns. |
| platform | Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok). |
