The response reference lists every field, its type and when it is null. See the full schema.
Null means unknown
A field Kwai doesn't show is null, never zero or an empty string, so a real zero always means zero.
What it accepts
The Kwai post: a link (kwai.com/@KwaiBrasilOficial/video/5217007328706437238, /video/<id>, /embed/<id>, /search/<words>/video/<id>, /@<name>/photo/<id>, m.kwai.com/photo/<user>/<id>, snackvideo.com), a share link (k.kwai.com/p/<code>, s.kw.ai, kw.ai, kwai-video.com, s.kwai.app/s/<code>) or a bare post ID.
Write one parser
Kwai, TikTok, Instagram and 18 more platforms answer in these fields, so the code that reads one reads them all.
platformstring- Platform ID (tiktok, youtube, …).
idstring- Platform-native post ID (string; Instagram shortcode, Reddit with its t3_ prefix).
urlstring- Canonical post URL.
typestring- Normalized content shape. New values may be added; treat unknown values as other.
platform_typestring- The platform's own product label, lowercase (reel, short, story, live, tweet, …).
titlestring- Headline (YouTube title, Reddit title); null on caption-only platforms.
textstring- Caption, description or body as plain text.
languagestring- BCP-47 language of text, when the platform states it.
Live data from 33 platforms.
What teams build with the Kwai Post API.
Turn a shared link into caption and video
Track a video's views and shares over time
Find the sound or topic a video uses
Resolve share links to the post and author
Good to know before you build.
- metrics.share_count is what Kwai calls forwards.
- is_pinned is null here, because only the account's list says which posts are pinned. The Kwai User Posts API returns it.
- A share link can name an account instead of a post. That returns invalid_input, with the account's link in details.resolved_url. A dead share link returns not_found.
- Old /picture/ links that search engines still index return not_found, because Kwai no longer serves them as posts. So not_found also covers an ID Kwai's own site doesn't serve as a post, not only a deleted one.
- The sound, the tags Kwai adds, the place, the topic, author_user_id and duet_source come from a second request. If it fails, they are null and a partial_data warning says so.
