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.

Use the group_topic action on Douban. Accepts these parameters: url and max_replies. Returns these fields: group_name, text, author_url, and author_name.

Price $1.39 per 1,000 requests ($0.001389 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 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.
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.
group_idKeeps the platform's own meaning
group_nameKeeps the platform's own meaning
group_urlKeeps the platform's own meaning
author_nameAuthor's display name.
author_urlLink to the author's profile on the source platform.
reply_countReplies, usually replies to a comment. null means not disclosed.
repliesKeeps the platform's own meaning
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.
platformSource 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
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).

  • Douban Groups: Reading Topics Is Distinct from Member Management ↗

    Douban Help lists joining groups, pinning topics, and managing members as distinct features, with certain actions requiring group leader or administrator permissions. Fetching specific topics here and citing management documentation does not grant those permissions, nor does it provide join, post, or management operations.
