Read the answers under one Zhihu question from its link, an answer link or the question ID, up to 20 per call, 20 by default. Each answer has full text, upvotes, comments, saves, thanks, publish and edit times, and the author's name, bio, followers and verification. Sort by Zhihu's default order or by most recently updated. Only the first page is available.

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 Answers to a question endpoint (zhihu/question_answers).

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 question_answers, and put the parameters inside params.
- Required parameters:
  - url: A Zhihu question link (https://www.zhihu.com/question/<question ID>), a link to an answer under that question, or the numeric question ID.
- Optional parameters:
  - sort: Answer order: default follows Zhihu's own order (default) and updated puts the most recently updated answers first. (allowed: default / updated)
  - limit: The most rows to return in this call, an integer from 1 to 20. 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, type, url, question_id (ID of the question the answer belongs t…), title, text, like_count, comment_count, collect_count, thanks_count (Thanks the answer has received (questio…), posted_at, updated_at (When the answer was last edited (questi…); 19 fields in total, full list at https://api.everyinfra.com/api/v1/social/catalog?platform=zhihu.
- Example request body:
{
  "platform": "zhihu",
  "action": "question_answers",
  "params": {
    "url": "https://www.zhihu.com/question/265808959"
  }
}
- 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.
`question_id`	ID of the question the answer belongs to (question_answers), the same as the requested question.
`title`	Title. null when the platform has no titles (for example text-only posts).
`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).
`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.
`collect_count`	Saves or favorites. null means not disclosed, not 0.
`thanks_count`	Thanks the answer has received (question_answers).
`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.
`updated_at`	When the answer was last edited (question_answers), ISO 8601 in UTC; the same as posted_at when never edited.
`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.
