Etsy Search API

Please help me write a data collection script with the EveryInfra Etsy Search endpoint (etsy/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 etsy and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies the search query string for Etsy product searches (for example, ceramic mug) to query item titles and listings. It is not an exact match shop lookup; use shop to retrieve shop profiles or reviews.
- Optional parameters:
  - currency: Sets the listing price currency in search results using one of the supported lowercase currency codes, defaulting to usd. The min_price parameter is interpreted in this currency. (allowed: aud / brl / cad / chf / dkk / eur / gbp / hkd)
  - exclude_keywords: Excludes items whose titles contain any specified string in this array (for example, ["digital", "download"]). Comparisons are case-insensitive.
  - min_price: Filters Etsy product search results by minimum listing price using a non-negative number in the specified currency. It does not represent minimum order quantities, maximum shipping charges, or request budget limits.
  - sort: Controls product search result ordering for the Etsy search action. Supported values are relevance (default), price_asc, price_desc, and newest. (allowed: newest / price_asc / price_desc / relevance)
  - limit: The most rows to return in this call, an integer from 1 to 50. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 20)
- Returns a list of records. Main fields of each record: listing_id, title, url, price, list_price, currency, rating, rating_scale, shop_id, shop_name, shop_rating, shop_review_count; 16 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=etsy.
- Example request body:
{
  "platform": "etsy",
  "action": "search",
  "params": {
    "keyword": "ceramic mug"
  }
}
- 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.
