Google Shopping Search API

Please help me write a data collection script with the EveryInfra Google Shopping Search endpoint (google_shopping/search).

How the endpoint works:
- 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 google_shopping and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: The product search term, such as wireless earbuds.
- Optional parameters:
  - country: A two-letter country code such as us, gb or de for the Google Shopping market to search (default us). Prices are in that market's currency.
  - language: A two-letter language code such as en or de for titles and labels (default en).
  - max_price: The highest price to include; not below min_price.
  - min_price: The lowest price to include, in the currency of the country market; 0 or more.
  - sort: Sort order: price_low (price low to high), price_high (price high to low) or rating (best rated first). Leave it out for relevance.
  - limit: The most rows to return in this call, an integer from 1 to 100. 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: rank, title, product_id (Google Shopping product ID (digits) tha…), offer_id, image_id, price_text (Price as displayed, with currency symbo…), price (The number parsed from price_text, in t…), old_price_text, old_price, merchant (The merchant whose offer this row shows), multiple_merchants (Whether more than one merchant sells th…), rating; 16 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=google_shopping.
- Example request body:
{
  "platform": "google_shopping",
  "action": "search",
  "params": {
    "keyword": "wireless earbuds"
  }
}
- Price: $0.56 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.
