SEEK Search API

Please help me write a data collection script with the EveryInfra SEEK Search endpoint (seek/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 seek and action to search, and put the parameters inside params.
- Required parameters:
  - keyword: Specifies job search keywords (e.g., software engineer) for SEEK search. Used in combination with location to target postings; does not query company profiles.
- Optional parameters:
  - country: Selects the job market using the full lowercase country name. Allowed values are australia (default), new zealand, hongkong, indonesia, malaysia, philippines, singapore, and thailand. NZ is not read as New Zealand. (allowed: australia / hongkong / indonesia / malaysia / new zealand / philippines / singapore / thailand)
  - location: Specifies a city or region within the selected market, such as Sydney NSW. This is not a country code replacement for country.
  - sort: Sorts job search results. Allowed values are relevance (keyword match) and newest (posting date). Sorting by salary is not supported. (allowed: newest / relevance)
  - 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, company_name, location, posted_at, employment_type, is_remote, salary, text, category, applicant_count; 24 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=seek.
- Example request body:
{
  "platform": "seek",
  "action": "search",
  "params": {
    "keyword": "data analyst"
  }
}
- 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.
