See which App Store search keywords 2 to 10 apps all rank for, from their numeric IDs in app_ids. Each row is one shared keyword with its search volume, how many apps that search returns, and in rankings each app's position and title. US store only. 20 keywords by default, up to 100.

Price $11.51 per 1,000 requests ($0.01151 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

AI prompt

Please help me write a data collection script with the EveryInfra App Store Keyword intersection endpoint (app_store/keyword_intersection).

How the endpoint works:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to app_store and action to keyword_intersection, and put the parameters inside params.
- Required parameters:
- app_ids: The apps for bulk_metrics (1 to 20) or keyword_intersection (2 to 10), as an array or a comma-separated string of Apple numeric IDs, the digits after id in an app link, such as 324684580. Only the US store is covered.
- Optional parameters:
- country: Storefront for keyword_intersection. Only the US store is covered: leave it out or pass us; any other country is rejected before the call runs.
- limit: 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. (default: 20)
- Returns a list of records. Main fields of each record: keyword (A search keyword the app ranks for (key…), search_volume (Search volume of the keyword in the US…), search_result_count (How many apps the store returns for the…), ranked_at (When the rank and search volume for thi…), rankings, total_keywords (How many keywords the app ranks for in…).
- Example request body:
{
"platform": "app_store",
"action": "keyword_intersection",
"params": {
"app_ids": [
"324684580",
"1017492454"
]
}
}
- Price: $11.51 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

Request parameters

Name	In	Type	Required	Default	Description
`Authorization`	header	`string`	Yes	-	Bearer followed by your API key. Create it in the console; never put it in a URL or a code repository.
`platform`	body	`string`	Yes	`app_store`	Platform identifier, fixed value.
`action`	body	`string`	Yes	`keyword_intersection`	Capability identifier, fixed value.
`app_ids`	body.params	`array`	Yes	-	The apps for `bulk_metrics` (1 to 20) or `keyword_intersection` (2 to 10), as an array or a comma-separated string of Apple numeric IDs, the digits after id in an app link, such as `324684580`. Only the US store is covered. On `bulk_metrics` each app gets one row and an app without data is left out; on `keyword_intersection` each row is one keyword they all rank for. Any other count is rejected before the call runs.
`country`	body.params	`string`	No	-	Storefront for `keyword_intersection`. Only the US store is covered: leave it out or pass us; any other country is rejected before the call runs.
`limit`	body.params	`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

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

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_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.
`rankings`	Keeps the platform's own meaning
`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).
