Weibo Posts by user API

Please help me write a data collection script with the EveryInfra Weibo Posts by user endpoint (weibo/user_posts).

How the endpoint works:
- 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 weibo and action to user_posts, and put the parameters inside params.
- Required parameters:
  - user_id: The account's numeric Weibo UID, or a profile link containing /u/<UID>. Nicknames are not accepted; find the UID with user_search first.
- Optional parameters:
  - page_token: Page token for user_posts. Leave it out for the first page, then pass back the previous response's next_page_token exactly as received, with the other parameters unchanged.
  - post_type: Which posts user_posts returns: all (default), original for the account's original posts, video or image. (allowed: all / image / original / video)
- Returns a list of records. Main fields of each record: id, url, text, posted_at, device (Client the post was published from (suc…), repost_count, comment_count, like_count, view_count (Read count Weibo shows for the post (po…), is_repost (Whether the post is a repost), original_post_id (For a repost, the ID of the original po…), is_long_text (Whether the post is a long post (post_d…); 25 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=weibo.
- Example request body:
{
  "platform": "weibo",
  "action": "user_posts",
  "params": {
    "user_id": "1749127163"
  }
}
- Price: $0.81 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.
