Find the Amazon US search keywords that 2 to 10 products all rank for, passing their ASINs in asins. Each row is one shared keyword with its monthly search_volume, and rankings shows every product's position on that results page, organic or sponsored, with its price and rating. 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 Amazon Keyword intersections endpoint (amazon/keyword_intersections).

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 amazon and action to keyword_intersections, and put the parameters inside params.
- Required parameters:
  - asins: 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.
- Optional parameters:
  - 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: one the product ranks…), search_volume (Estimated monthly searches for the keyw…), ranked_at (When the position was seen, ISO 8601 in…), rankings, total_keywords (How many keywords the product ranks for…).
- Example request body:
{
  "platform": "amazon",
  "action": "keyword_intersections",
  "params": {
    "asins": [
      "B0C2JXSHSK",
      "B0CM8STPNH"
    ]
  }
}
- 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	`amazon`	Platform identifier, fixed value.
`action`	body	`string`	Yes	`keyword_intersections`	Capability identifier, fixed value.
`asins`	body.params	`array`	Yes	-	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`	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: 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`	Keeps the platform's own 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).
