Coming soon

This endpoint is listed but not callable yet: a call answers capability_paused and is not charged. The parameters, fields and price on this page are the contract it will open with; the status page and the changelog say when it does.

Known limits

  • About 10 comments come back per page; the platform sets the page size, so there is no page-size parameter.
  • For the next page, pass page.next_cursor back as cursor. A cursor stays valid for 24 hours. When page.has_more is false there is nothing left.

Returned fields

data.items is a list of Comment.

FieldTypeViewDescription
idstringcompactComment ID.
post_idstringcompactID of the post it is under.
parent_idstring | nullcompactThe comment it replies to; null for top-level comments.
textstringcompactComment text.Long text: view=compact may shorten it.
published_atstringcompactWhen it was posted, ISO 8601 in UTC.

likesinteger | nullcompactLikes on the comment.
repliesinteger | nullcompactReplies under it.
ip_locationstring | nullstandardRegion label the platform shows next to the comment, if any.
extobjectfullPlatform-specific extras. Only returned with view=full.

The view column is the smallest view a field comes back in: compact returns only compact fields, standard adds the standard ones, full returns everything. The default is standard.

When it is charged

One call costs $0.002 and returns one page of about 10 comments. Collecting 1,000 comments takes about 100 calls, $0.20 in total. Each page is a separate call; failed calls are not charged.

Common errors

Every error has the same shape and says whether it was charged. The ones this endpoint can return:

HTTPCodeMeaningCharged
400invalid_paramsA parameter is missing, has the wrong type or value, or the method is wrong. problems lists each one; param names the first.Retry: after a fixno
400cursor_mismatchThe cursor was sent to another endpoint, or with other parameters than the page it came from (view and fields may change).Retry: after a fixno
401unauthorizedThe key is missing, malformed, revoked, disabled or expired (reason says which when known).Retry: nono
402insufficient_balanceThe balance (available) cannot cover the most this call could cost (required).Retry: after a fixno
404not_foundThe post, account or page does not exist or is not public. Endpoints whose charge_when_not_found is above 0 charge this answer (the source billed us for it): the body then says charged: true and amount.Retry: nono
410cursor_expiredThe cursor is older than the endpoint's cursor lifetime (page.cursor_expires_at said when).Retry: nono
429rate_limitedThe account sent too many requests this minute (reason: rate) or has too many calls running (reason: concurrency).Retry: yesno
500settlement_unknownThe data came back, but the charge could not be confirmed.Retry: with the same Idempotency-Keyunknown until looked up
502upstream_failedEvery data source for this endpoint failed on this request.Retry: yesno
503capability_pausedThis endpoint is paused right now; nothing ran.Retry: yesno
504timeoutThe data did not come back in time. The hold was released, so nothing was charged.Retry: yesno

Questions

Can I call the Zhihu answer comments API now?

This endpoint is listed but not callable yet: a call answers capability_paused and is not charged. The parameters, fields and price on this page are the contract it will open with; the status page and the changelog say when it does.

How much does the Zhihu answer comments API cost?

One call costs $0.002 and returns one page of about 10 comments. Collecting 1,000 comments takes about 100 calls, $0.20 in total. Each page is a separate call; failed calls are not charged.

How do I get the next page?

Pass page.next_cursor from the response back as the cursor parameter. When page.has_more is false there is nothing left. Every page is its own call at $0.002.

Do I need a Zhihu account, cookies or a QR login?

No. You send only your okdata API key. The data is public data from Zhihu; nothing is fetched with your own Zhihu account.

Am I charged when a call fails?

No. Every error response says charged: false, except a timeout, which says charged: null until the outcome is known. Resend with the same Idempotency-Key and you are never charged twice.

What if Zhihu does not show a field?

The field is null, and meta.unavailable names it with the reason: platform (the platform never shows it) or capability (we cannot fetch it yet).
