Kuaishou Comments API

The comments under one video.

Get the comments under any public Kuaishou video and get back text, likes and time, as JSON over HTTP or from your AI client over MCP. A call to the Kuaishou Comments API costs 2 credits ($0.004 to $0.0067 depending on the pack), failed calls are free, and the response has the same format as every other call. Last tested 2026-10-30.

Need 100 items? Send limit: 100 and one call pages for you: at most 3 pages, 6 credits. It stops once it has them or the list ends; pages it does not use are not charged, and neither are pages that fail. Reading 1,000 items comes to about 50 credits, about $0.17.

Daily watch: tell your AI “watch this daily” and this call runs by itself every day, sending only what is new: at most 62 credits a month, about $0.21. How to set it up

What you get from the Kuaishou Comments API.
From a recorded answer.

A recorded call returned 40 items; here is the first, field by field. Names and text are removed from the sample; the numbers are as recorded.

Lighter for your AI: the same recorded data (40 items) is about 15,345 tokens as the platform's raw JSON and about 4,811 as this interface returns it, 68% fewer (measured 2026-11-06). How it was measured

Kuaishou Comments API parameters.
5 parameters, 1 required.

Send them as a JSON body with POST. Your key goes in the Authorization header, never in the URL.

NameTypeRequiredDefaultDescription
platformstringRequired—Always "kuaishou" on this page.
idstringOne of these—Video ID: the part of the video's web link that starts with 3x. With only a link or a share text, give it as url
urlstringOne of these—Link to the video, pasted as it is: the https://www.kuaishou.com/short-video/… web link, the v.kuaishou.com short link the app copies, or a whole share text with one of these in it. A short link is opened once to see which video it leads to
reply_ofstringOptional—When given, returns the replies under one comment (2 credits).
cursorstringOptional—Pass page.cursor from the last response to get the next page.

Where to get what you send.

id

Video ID: the part of the video's web link that starts with 3x. With only a link or a share text, give it as url (e.g. 3x5pf8ia4zc76tc)

Every item these return carries its ref; send it as it is:

Or send the web link: the url field of the same items.

Kuaishou Comments API response fields.
What Kuaishou cannot give is marked.

FieldTypeMeaning
items[].urlstringalways nullA link to the comment, where the platform has one.
items[].textstringThe comment itself.
items[].published_atstringWhen it was posted, ISO 8601 in UTC.
items[].author.labelstringAn anonymous label, stable within one response. Whoever wrote it is never named.
items[].metrics.likesintegerLikes.
items[].reply_countintegeralways nullHow many replies it has.
items[].content_idstringalways nullThe item the comment is under.
items[].parent_idstringThe comment it replies to directly; null for a top-level comment.
items[].root_idstringThe top-level comment its thread hangs under.
nullFields Kuaishou cannot give

Read null as “Kuaishou did not give this”, not as zero. These are always null on this call:

  • urlA link to the comment, where the platform has one.
  • reply_countHow many replies it has.
  • content_idThe item the comment is under.
Other values of this call

Send the parameter and the call returns something else:

reply_ofthe replies under one comment2 credits

Compared with the Douyin Comments API, this call does not give reply count.

Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format

Kuaishou Comments API: paging and billing.

One call returns a page of up to 40 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes.
A call that runs and finds nothing is a successful call: status is "empty", items is empty, and it costs 2 credits.
On this call Kuaishou cannot tell a video that does not exist from one with no data: both come back as empty, and both are charged.

5 calls per second per key, 20 after a purchase; going over is not charged. Rate limits

A failed call costs 0 credits and is never retried on its own. Error codes

“Last tested” above is the last day a real call of this interface succeeded. Each call reads from the platform, and fetched_at in the answer is when it was read. The same request sent again with the same key within 5 minutes is a replay (replayed: true): 0 credits, and the answer as first read.

Kuaishou Comments API: questions.
Short answers.

All Kuaishou data APIs
Do I need a Kuaishou account or Kuaishou's own API access?
No. You only need a SocialToAI key. The call returns content and account information publicly visible on Kuaishou; you never sign in to Kuaishou or apply for anything there.
Can I get the replies under one comment?
Yes: send reply_of in the request. That call costs 2 credits.
What does one call cost in dollars?
2 credits: $0.0067 at 300 credits per dollar (purchases from $10), $0.004 at 500 per dollar (from $200). Credits never expire and there is no subscription. 100 free credits on sign-up, no card.
Am I charged when a call fails or finds nothing?
A failed call costs 0 credits and is never retried on its own. A call that runs and finds nothing is a successful call: status is "empty" and it costs 2 credits. This interface cannot tell a target that does not exist from one with no data, so both are charged as empty.
How much does one call return?
One call returns a page of up to 40 items. When page.has_more is true, send page.cursor back as cursor for the next page; each page costs 2 credits and a cursor works for 30 minutes.
Is there a rate limit?
5 calls a second per key, 20 a second after your first purchase. A request over the limit is told how long to wait and is not charged.
How do I use it from Claude, ChatGPT or Cursor?
Yes. In Claude or ChatGPT, add the MCP address https://mcp.socialtoai.com/mcp as a custom connector, sign in with the code we email you and press Allow; there is no key to paste. In Claude Code, run one command, type /mcp, pick socialtoai and sign in; Codex and Cursor sign in too, with their steps on the connect page. Then ask in plain words and your AI calls comments for you.
