Yandex Market API

Please help me write a data collection script with the EveryInfra Yandex Market endpoint (yandex/market).

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 yandex and action to market, 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:
  - city: Specifies the target city slug (e.g., moscow, saint_petersburg) for the Yandex market action. Must match an allowed enum value and cannot be substituted for location on map searches. (allowed: chelyabinsk / kazan / krasnodar / krasnoyarsk / moscow / nizhny_novgorod / novosibirsk / omsk)
  - 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.
  - 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.
  - region: Accepts a numeric city region code for the Yandex market action, defaulting to 213 (Moscow). This is an internal region identifier, not an RU country code. Providing an explicit city parameter overrides this setting.
  - 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: popular / top_rated)
  - 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, title, price, currency, rating, rating_scale, rating_count, review_count, purchase_count, category, shop_name; 16 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=yandex.
- Example request body:
{
  "platform": "yandex",
  "action": "market",
  "params": {
    "keyword": "ноутбук"
  }
}
- 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.
