The [response reference](https://socialtap.dev/docs/reference/kwai/post/index.md#response) lists every field, its type and when it is `null`. [See the full schema](https://socialtap.dev/resources/post/index.md). - ### 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/\, /embed/\, /search/\/video/\, /@\/photo/\, m.kwai.com/photo/\/\, snackvideo.com), a share link (k.kwai.com/p/\, s.kw.ai, kw.ai, kwai-video.com, s.kwai.app/s/\) 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. - **`platform`string**: Platform ID (tiktok, youtube, …). - **`id`string**: Platform-native post ID (string; Instagram shortcode, Reddit with its t3_ prefix). - **`url`string**: Canonical post URL. - **`type`string**: Normalized content shape. New values may be added; treat unknown values as other. - **`platform_type`string**: The platform's own product label, lowercase (reel, short, story, live, tweet, …). - **`title`string**: Headline (YouTube title, Reddit title); null on caption-only platforms. - **`text`string**: Caption, description or body as plain text. - **`language`string**: BCP-47 language of text, when the platform states it.

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. ## 1 credit per request. Failed requests are free. Buy credits once and spend them on any endpoint, on any platform.
