Booking Prices API

Please help me write a data collection script with the EveryInfra Booking Prices endpoint (booking/prices).

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 booking and action to prices, and put the parameters inside params.
- Required parameters:
  - url: Specifies the full URL to a single property page, preferably using the /hotel/ path format. Used by profile to fetch details, reviews to retrieve property reviews, and prices to check room rates.
- Optional parameters:
  - adults: Specifies the adult guest count for price queries, accepting an integer and defaulting to 2. Used as a price query parameter only; does not cap returned room options or initiate a booking.
  - check_in: Specifies the check-in date in YYYY-MM-DD format. Search and profile actions require both check_in and check_out to send stay dates. For prices, this acts as the start date when start_date is omitted.
  - currency: Specifies the currency for property price displays, defaulting to USD. Accepts listed lowercase codes for search and profile actions, and uppercase three-letter codes for prices.
  - days: Specifies how many calendar days ahead to query for prices, defaulting to 7 and constrained to 1–30 (values outside this range are clamped).
  - rooms: Specifies the number of rooms for price queries, accepting an integer and defaulting to 1. Determines the requested room count rather than the number of returned room options.
  - start_date: Specifies the start date for daily price lookups in prices using YYYY-MM-DD format. Overrides check_in when both are provided. Does not represent review posting dates or property opening dates.
  - limit: The most rows to return in this call, an integer of 1 or more. The default applies when you leave it out, and a call can return fewer rows.
- Returns a list of records. Main fields of each record: id, url, hotel_name, room_name (Room type name), check_in, check_out, price, original_price, discount_percent, currency, taxes_included, is_sold_out; 23 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=booking.
- Example request body:
{
  "platform": "booking",
  "action": "prices",
  "params": {
    "url": "https://www.booking.com/hotel/jp/park-hyatt-tokyo.html"
  }
}
- 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.
