Yandex Search API

Please help me write a data collection script with the EveryInfra Yandex Search endpoint (yandex/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 yandex and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies search terms for Yandex actions, targeting local places in search and e-commerce items in market. Map listings and product catalogs query separate underlying datasets.
- Optional parameters:
  - category: Filters place categories for the Yandex search action (e.g., restaurants, cafes, coffee_shops, hotels, or none to clear). (allowed: atms / auto_repair / banks / bars_pubs / beauty_salons / burgers / cafes / car_wash)
  - lang: Sets the response language for the Yandex search action, accepting ru, en, kk, tr, or uk. This controls search interface locale and does not guarantee translation of user-generated review content. (allowed: en / kk / ru / tr / uk)
  - language: Sets the fallback interface language for Yandex actions, defaulting to ru for search and en for reviews. Explicitly passing lang on the search action overrides this parameter.
  - location: Sets the target city for the Yandex search action, defaulting to Moscow. This parameter takes city names and is distinct from numeric Yandex Market region IDs.
  - max_price: Sets the upper price boundary for the targeted Yandex action when used in conjunction with min_price. It does not filter by maximum user rating. Filtering uses whole numbers: decimals round up (145.98 becomes 146).
  - min_price: Sets the lower price limit for Yandex actions, representing product price on market and local place price tier on search. These values reflect target-platform price points rather than API usage fees.
  - sort: Controls sorting order per Yandex action. Accepts relevance or distance for search; popular or top_rated for market; and newest (default), relevance, top_rated, or lowest_rated for reviews. (allowed: distance / 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: id, url, name, text, address, city, country, categories, rating, rating_scale, review_count, phone; 16 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=yandex.
- Example request body:
{
  "platform": "yandex",
  "action": "search",
  "params": {
    "keyword": "музей Санкт-Петербург"
  }
}
- 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.
