Instagram Post details API

Please help me write a data collection script with the EveryInfra Instagram Post details endpoint (instagram/post).

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 instagram and action to post, and put the parameters inside params.
- Required parameters:
  - urls: Accepts an array of full Instagram post or Reel URLs (e.g., /p/<shortcode>/ or /reel/<shortcode>/) for the post action, billed per target URL. Unlike post, the comments action processes only a single URL.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 11. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. (default: 11)
- Returns a list of records. Main fields of each record: post_id, url, text, media_type, like_count, comment_count, view_count, author_username, author_name, posted_at, location, author_follower_count; 14 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=instagram.
- Example request body:
{
  "platform": "instagram",
  "action": "post",
  "params": {
    "urls": [
      "https://www.instagram.com/p/<POST_SHORTCODE>/"
    ]
  }
}
- Price: $0.56 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.
