Etsy Shop API

Please help me write a data collection script with the EveryInfra Etsy Shop endpoint (etsy/shop).

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 etsy and action to shop, and put the parameters inside params.
- Required parameters:
  - shop: Identifies the shop using either its short name or a full URL like https://www.etsy.com/shop/<shop_name>. For the reviews action, it returns shop-level reviews rather than individual listing reviews.
- Optional parameters:
  - shop_name: Serves as a compatibility input representing the Etsy shop short name. The required primary shop parameter must still be included in calls to the reviews or shop actions.
  - username: Acts as a fallback compatibility input for the shop short name with lower precedence than shop and shop_name. It does not represent a buyer username, and the required shop parameter must still be supplied.
- Returns one object. Main fields: shop_id, shop_name, shop_url, is_star_seller, active_listing_count, on_etsy_since, location.
- Example request body:
{
  "platform": "etsy",
  "action": "shop",
  "params": {
    "shop": "GlassMystique"
  }
}
- 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.
