Zillow ZIP code search API

Please help me write a data collection script with the EveryInfra Zillow ZIP code search endpoint (zillow/zip_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 zillow and action to zip_search, and put the parameters inside params.
- Required parameters:
  - zip: A US ZIP code for zip_search, preferably a five-character string so leading zeros are preserved. A comma- or whitespace-separated string and a ZIP-code array are also accepted.
- Optional parameters:
  - days_on_zillow: A zip_search time preset: empty for no restriction; 1, 7, 14, 30, or 90 for days; or 6m, 12m, 24m, or 36m for months. It generally means time listed, but for sold homes it means time since sale. (allowed: 1 / 12m / 14 / 24m / 30 / 36m / 6m / 7)
  - for_rent: A JSON boolean that includes rental listings in zip_search. It is not exclusive and can be combined with other status filters. Do not send the string "false".
  - for_sale_by_agent: A JSON boolean that includes agent-listed homes in zip_search. It defaults to true only when no sale-by-owner, rental, or sold status is selected; selecting another status removes that implicit default.
  - for_sale_by_owner: A JSON boolean that includes owner-listed homes in zip_search. It does not prove that a transaction has no commission or intermediary cost.
  - max_price: The maximum listing-price filter for search and zip_search. In zip_search, it overrides price_max. It is not the upper bound of a Zillow home-value estimate.
  - min_price: The standard minimum-price field for search and zip_search. In zip_search, it overrides price_min. It is not an agent service fee.
  - sold: A JSON boolean that includes sold homes in zip_search. Selecting it does not guarantee that every area exposes a public sale amount.
  - 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: zpid, url, status, status_type, price, currency, address, street, city, state, zipcode, latitude; 29 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=zillow.
- Example request body:
{
  "platform": "zillow",
  "action": "zip_search",
  "params": {
    "zip": "78701"
  }
}
- 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.
