Check how often shoppers search Amazon US for up to 20 keywords in one request. Pass them in keywords as an array or a comma-separated string; each row gives one keyword and its estimated monthly search_volume. Case is ignored and duplicates count once. Keywords with too few searches get no row.

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.

Please help me write a data collection script with the EveryInfra Amazon Keyword search volume endpoint (amazon/bulk_search_volume).

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 bulk_search_volume, and put the parameters inside params.
- Required parameters:
  - keywords: The keywords for bulk_search_volume: 1 to 20, as an array or a comma-separated string, each up to 80 characters and 10 words, such as standing desk. Case is ignored and repeats count once.
- Optional parameters:
  - limit: The most rows to return in this call, an integer of 1 or more. The default applies when you leave it out, and a call can return fewer rows.
- 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…).
- Example request body:
{
  "platform": "amazon",
  "action": "bulk_search_volume",
  "params": {
    "keywords": [
      "wireless headphones",
      "yoga mat",
      "portable blender"
    ]
  }
}
- 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	`bulk_search_volume`	Capability identifier, fixed value.
`keywords`	body.params	`array`	Yes	-	The keywords for `bulk_search_volume`: 1 to 20, as an array or a comma-separated string, each up to 80 characters and 10 words, such as `standing desk`. Case is ignored and repeats count once. Only Amazon US search volume is covered; more than 20 keywords, or one that is too long, is rejected before the call runs.
`limit`	body.params	`integer (1–)`	No	-	The most rows to return in this call, an integer of 1 or more. The default applies when you leave it out, and a call can return fewer rows.

  "id": "req_…",
  "platform": "amazon",
  "action": "bulk_search_volume",

    {

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.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
