Page through a Zhihu user's pins (short posts), newest first, 20 per page. Each pin has its text, images, likes, comments, reposts, saves and publish time.

Price $0.81 per 1,000 requests ($0.000806 per call). Failed calls and empty results are not charged. Synchronous. For slow jobs add "mode": "async" to the body, take the job_id and poll.

Please help me write a data collection script with the EveryInfra Zhihu User pins endpoint (zhihu/user_pins).

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 zhihu and action to user_pins, and put the parameters inside params.
- Required parameters:
  - url: A Zhihu profile link (https://www.zhihu.com/people/<profile ID>) or the profile ID alone. Nicknames are not accepted.
- Optional parameters:
  - page_token: Page token. Leave it out for the first page, then pass back the previous response's next_page_token exactly as received. 20 pins per page, newest first; each page is one call.
- Returns a list of records. Main fields of each record: id, type, url, text, image_urls (Images in the pin (user_pins)), like_count, comment_count, repost_count (Times the pin was reposted (user_pins)), collect_count, posted_at, author_id, author_name; 15 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=zhihu.
- Example request body:
{
  "platform": "zhihu",
  "action": "user_pins",
  "params": {
    "url": "https://www.zhihu.com/people/zhihuadmin"
  }
}
- 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.

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

Field	Meaning
`id`	The record's unique ID on the platform. Unique only within one platform; IDs can repeat across platforms.
`type`	Record type; values depend on the capability (for example video / image / text).
`url`	Link to the record on the platform.
`text`	Body text with HTML removed, returned in full and never cut short (on a few platforms the list results themselves carry only an excerpt; the platform's field notes say so).
`image_urls`	Images in the pin (user_pins); absent for text-only pins.
`like_count`	Likes. null means the platform or this capability does not disclose it; it is not 0.
`comment_count`	Comments. null means not disclosed, not 0.
`repost_count`	Times the pin was reposted (user_pins).
`collect_count`	Saves or favorites. null means not disclosed, not 0.
`posted_at`	Publish time in ISO 8601, UTC (for example 2026-08-07T12:34:56+00:00). Non-standard strings from the platform are passed through as is, so parse defensively. null means the platform does not disclose it.
`author_id`	Author's unique ID on the platform.
`author_name`	Author's display name.
`author_url`	Link to the author's profile on the platform.
`author_avatar_url`	Author avatar URL; on comment results, the commenter's avatar.
`author_follower_count`	Author's follower count. null means not disclosed.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
