Google Play Reviews API

Please help me write a data collection script with the EveryInfra Google Play Reviews endpoint (google_play/reviews).

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 google_play and action to reviews, and put the parameters inside params.
- Required parameters:
  - app_id: The Android package name from the ?id= value of a Play Store URL, such as com.example.app. It is not an Apple App Store numeric ID. Pass the package name, not the full Play URL.
- Optional parameters:
  - country: Selects the Google Play storefront country or region using a lowercase code such as us. The default is us.
  - language: Selects the language used for Play Store content and review queries, such as en or zh. The default is en. It does not change country automatically or guarantee that every returned review was written in that language.
  - page_token: Pagination token: pass back next_page_token from the previous response to get the next page; omit it for the first page. Keep every other parameter unchanged. Tokens last 24 hours and each page is one call.
  - sort: The app-review order: newest for recent reviews or top_rated for higher-rated reviews; reviews default to newest. (allowed: newest / top_rated)
  - limit: The most rows to return in this call, an integer from 1 to 200. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 40)
- Returns a list of records. Main fields of each record: id, app_id, text, title, score, author_name, author_avatar_url, thumbs_up, reply_text, reply_at, app_version, language; 14 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=google_play.
- Example request body:
{
  "platform": "google_play",
  "action": "reviews",
  "params": {
    "app_id": "com.whatsapp"
  }
}
- Price: $1.39 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.
