How health is measured
  • Health = the share of calls that returned data, in percent. Empty results, failures and unknown outcomes do not count as returning data.
  • Levels: 90% and above is healthy, 70% and above is available, 40% and above is limited; anything lower is mostly down.
  • A period (the last 24 hours, one hour or one day) gets a score only once it has at least 50 calls. Periods with fewer calls show as normal: a few failures among a handful of calls do not mean the API is down.
  • Calls include real customer calls and our own daily probe calls. Request errors (wrong parameters, no balance) are excluded.
  • Average time counts only calls that completed normally: response time for sync calls, acceptance to completion for async ones.

Search public results on Zhihu. Accepts these parameters: content_type, keyword, and sort. Returns these fields: author_avatar_url, title, author_verification_label, and comment_count.

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.

Response example

Real response

Captured September 26, 2026 at 08:56 (UTC) by calling this API with the parameters in the code sample above. results and count are that call's real response with personal information (names, handles, avatars, profile links, contact details) removed; the list keeps the first 2. id, billing and quota differ on every call, so only their shape is shown.

Response fields

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

FieldMeaning
idThe record's unique ID on the source platform. Unique only within one platform; IDs can repeat across platforms.
typeRecord type; values depend on the capability (for example video / image / text).
urlLink to the record on the source platform.
titleTitle. null when the platform has no titles (for example text-only posts).
textBody text with HTML removed. Long text may be truncated.
like_countLikes. null means the platform or this capability does not disclose it; it is not 0.
comment_countComments. null means not disclosed, not 0.
collect_countSaves or favorites. null means not disclosed, not 0.
posted_atPublish 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.
cover_image_urlKeeps the platform's own meaning
platformSource platform identifier, the same as platform in the request (for example xiaohongshu, tiktok).
author_idAuthor's unique ID on the source platform.
author_nameAuthor's display name.
author_urlLink to the author's profile on the source platform.
author_avatar_urlKeeps the platform's own meaning
author_bioKeeps the platform's own meaning
author_follower_countAuthor's follower count. null means not disclosed.
author_verifiedKeeps the platform's own meaning
author_verification_labelKeeps the platform's own meaning

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
Per-minute request limit reached. Wait for Retry-After and try again.
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).
