Realtor Property search API

Please help me write a data collection script with the EveryInfra Realtor Property search endpoint (realtor/property_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 realtor and action to property_search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies the search location for Realtor requests. For search, enter a city and state (e.g., Austin, TX) to find agents. For property_search, enter a 5-digit US ZIP code or a City, ST abbreviation.
- Optional parameters:
  - baths_min: Sets the minimum number of bathrooms. The value is used as an integer, so it cannot preserve a half-bath value such as 1.5.
  - beds_min: Sets the minimum number of bedrooms as an integer. It is not the total number of rooms in the property.
  - city: Overrides the city name for property_search. Do not pass a conflicting city when searching by ZIP code to avoid generating contradictory location conditions.
  - max_price: Specifies the maximum listing price for the standard input and takes precedence over price_max in the same request. Interpret prices separately for sale and rental listings.
  - min_price: Specifies the minimum listing price for the standard input and takes precedence over price_min in the same request. This parameter filters property prices, not agent service fees.
  - sort: Listing order for property_search, always descending: newest (latest listings first, the default), price_desc (list price), sold_price_desc (sold price), recently_sold, bedrooms_desc, lot_size_desc, photo_count_desc, or… (allowed: bedrooms_desc / lot_size_desc / newest / photo_count_desc / price_desc / recently_sold / recently_updated / sold_price_desc)
  - status: One listing status for property_search, sent as a string; defaults to for_sale. Known values are sold, for_rent, ready_to_build, off_market, other, and new_community.
  - limit: The most rows to return in this call, an integer from 1 to 200. 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, status, price, sold_price, sold_at, listed_at, property_type, beds, baths, area_sqft; 28 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=realtor.
- Example request body:
{
  "platform": "realtor",
  "action": "property_search",
  "params": {
    "keyword": "10022"
  }
}
- 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.
