Xing Job details API

Please help me write a data collection script with the EveryInfra Xing Job details endpoint (xing/job_detail).

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 xing and action to job_detail, and put the parameters inside params.
- Required parameters:
  - url: Specifies the target XING URL. The job_detail action requires a /jobs/ link, while the profile action requires a /profile/ link; these object types cannot be used interchangeably.
- Returns one object. Main fields: id, url, title, company, company_url, location, country, salary_min, salary_max, salary_median, salary_currency, employment_type; 24 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=xing.
- Example request body:
{
  "platform": "xing",
  "action": "job_detail",
  "params": {
    "url": "https://www.xing.com/pages/sap"
  }
}
- 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.
