List the replies under one Zhihu comment, up to 100 per call, with text, likes, reply count, time and replier. Pass the content link plus a comment_id from a comments row whose reply count is above zero.

Price $0.56 per 1,000 requests ($0.000556 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.

AI prompt

Paste this into your AI assistant. It already holds this endpoint's parameters, response fields and an example request, so the assistant can ask what you need and then write the scraper.

Please help me write a data collection script with the EveryInfra Zhihu Comment replies endpoint (zhihu/comment_replies).

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 zhihu and action to comment_replies, and put the parameters inside params.
- Required parameters:
  - url: The content URL or profile URL required by content-oriented actions. content_detail and content_comments accept answer, article, or video links (question pages are not supported).
  - comment_id: The comment identifier required by comment_replies, taken from a content_comments row whose reply_count is non-zero.
- Optional parameters:
  - limit: The most rows to return in this call, an integer from 1 to 100. 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, text, like_count, posted_at, reply_count, author_id, author_name, author_avatar_url (Author avatar URL).
- Example request body:
{
  "platform": "zhihu",
  "action": "comment_replies",
  "params": {
    "url": "https://zhuanlan.zhihu.com/p/2032860336215307118"
  }
}
- 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.

Response example

Field preview

There is no real sample for these example parameters yet: this shows the response shape and fields from the contract, with … as placeholders. It is not the result of a real call.

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.
`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.
`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.
`reply_count`	Replies, usually replies to a comment. null means not disclosed.
`author_id`	Author's unique ID on the platform.
`author_name`	Author's display name.
`author_avatar_url`	Author avatar URL; on comment results, the commenter's avatar.
`platform`	Source platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).

Errors and billing

401: Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.
422: Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.
402: Insufficient balance. Top up first.
429: The account's per-minute request limit was reached (all of its API keys count together; a key's own lower limit applies first). Wait for Retry-After and try again; a rate package in the console raises the limit.
503: Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.
200 empty: The request completed without data and is not charged (billing.reason = empty_result_refunded).
