JD.com Product details API

Please help me write a data collection script with the EveryInfra JD.com Product details endpoint (jd/product_detail).

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 jd and action to product_detail, and put the parameters inside params.
- Required parameters:
  - item_id: Identifies one JD.com product for product_detail, reviews, or product_price. Pass the digit string returned by search or the canonical legacy URL https://item.jd.com/<digits>.html without a query or fragment.
- Returns one object. Main fields: item_id (JD numeric product ID), url, title, price, price_display (Price string exactly as shown on the JD…), price_masked (Whether JD masked the price on the deta…), currency, available (Whether the item could be bought when i…), unavailable_reason (Public reason JD shows when an item is…), shop_id (JD numeric shop ID), shop_name (Public shop name), shop_url (Public JD shop page); 31 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=jd.
- Example request body:
{
  "platform": "jd",
  "action": "product_detail",
  "params": {
    "item_id": "https://item.jd.com/100012043978.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.
