1688 In-platform product image search API

Please help me write a data collection script with the EveryInfra 1688 In-platform product image search endpoint (alibaba1688/image_search).

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 alibaba1688 and action to image_search, and put the parameters inside params.
- Required parameters:
  - image_url: For image_search, provide one public HTTPS product-image URL. The action submits one image, returns at most five matching 1688 offers, and does not include detail or SKU enrichment.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 5. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 5)
- Returns a list of records. Main fields of each record: id, url, title, price, currency, min_order_quantity (Minimum order quantity (MOQ)), order_count (Order count), supplier_name (Supplier name), image_url, rank (Position of the offer in this image's m…).
- Example request body:
{
  "platform": "alibaba1688",
  "action": "image_search",
  "params": {
    "image_url": "https://cbu01.alicdn.com/img/ibank/15418323391_1847764777.jpg"
  }
}
- Price: $5.56 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.
