AliExpress Rating summary API

Please help me write a data collection script with the EveryInfra AliExpress Rating summary endpoint (aliexpress/ratings).

Endpoint contract:
- 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 aliexpress and action to ratings, and put the parameters inside params.
- Required parameters:
  - url: Specifies the target AliExpress item using a full URL (such as https://www.aliexpress.com/item/<item_id>.html).
- Returns one object. Main fields: average_star, total_reviews, positive_rate, neutral_rate, negative_rate, five_star, four_star, three_star, two_star, one_star.
- Example request body:
{
  "platform": "aliexpress",
  "action": "ratings",
  "params": {
    "url": "https://www.aliexpress.com/item/3256806025886958.html"
  }
}
- 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.
