Kwai Scraper API
Kwai API: 3 endpoints for creator profiles, paginated post feeds, and single-video details from Brazil's biggest short-video app. Every request costs 1 credit on the standard tier — 100 free credits on signup, no card. Kwai publishes no official read API; SocialCrawl wraps it in the same x-api-key and unified schema as 45 other platforms, TikTok included.
TL;DR
The Kwai API by SocialCrawl returns Kwai data as structured JSON — 3 endpoints behind one x-api-key, from 1 credit per call. It shares one unified schema with 45 other platforms, so the same client code works everywhere.

What data does the Kwai API return?
Every endpoint returns structured JSON in a unified envelope. Computed fields such as engagement rate and content category are included only where the endpoint supports them and the required source inputs are present.

- avatar_url
- bio
- verified
- followers
- following

How to scrape Kwai in 3 steps
No proxies, no headless browsers, no login sessions. Send one authenticated GET request and read structured JSON back.
- 1
Get a free API key
Create an account and copy your key from the dashboard. Signup includes 100 free credits, and no card is required.
- 2
Call the Profile endpoint
Send a GET request with your key in the x-api-key header. Here is the full Kwai Profile request:
curl -H "x-api-key: YOUR_API_KEY" \ "https://www.socialcrawl.dev/v1/kwai/profile" - 3
Read the unified JSON
The response comes back in the shared SocialCrawl schema. Where the endpoint supports them and the required source inputs are present, fields such as engagement_rate and content_category are filled in too. Your client can rely on the shared envelope while treating enriched fields as optional.
Requirements and limits
Everything you need to know before your first Kwai call.
- Authentication
- One API key, passed in the x-api-key request header. No OAuth flow, no app review, and no per-platform credentials to manage.
- Pagination
- List endpoints return a next_cursor and a has_more flag. Pass the cursor back to page through results, with the same contract on every platform.
- Credits
- Calls start at 1 credits and are deducted per request. Every account starts with 100 free credits, and credits never expire.
- Rate limits
- There are no artificial rate limits. Your credit balance is the only throttle, so you can run requests concurrently as fast as you need.

}How does SocialCrawl handle 46 different platforms?
Social media scraping is hard. Schema normalization, authentication, rate limits, pagination — we handle it all before your data arrives.
Write once, query them all.
46 platforms return 46 different JSON shapes. We normalize every response into one consistent structure.
Metrics ready before you ask.
Normalized records include supported metrics such as engagement rate, estimated reach, content category, and language when the required source inputs are available.
One cursor, every platform.
Every platform paginates differently. We give you one consistent cursor-based system.
Fresh when it matters. Free on repeat.
Cache misses fetch current public data. Identical requests are cached for 2 to 30 minutes by data type and cost 0 credits on a hit; send Cache-Control: no-cache for a billed refresh.
Auth, proxies, and rate limits — handled.
Platform authentication, IP rotation, rate limit management — abstracted away. Just send a GET request.
What developers say
The unified schema saved us weeks of integration work. One parser handles every platform.
Our agents process social data from 46 platforms with zero platform-specific logic — one schema, end to end.
I paste an influencer's URL and get everything — followers, engagement rate, content categories — without touching code.
We switched from building our own scrapers. SocialCrawl handles the hard stuff, we focus on insights.
The computed fields alone — engagement_rate, estimated_reach, content_category — saved us an entire data pipeline.
How does SocialCrawl compare to DIY scraping for Kwai data?
Same Kwai data, two very different paths. Auth, rate limits, schema, and cost — side by side.
| Feature | SocialCrawl | DIY scraping |
|---|---|---|
| Setup | Sign up and send one GET request | Reverse-engineer kwai.com, then build proxies and parsers |
| Authentication | One x-api-key header | None — you manage IP rotation and bot detection yourself |
| Response schema | Unified JSON, same shape as TikTok and Instagram | Raw HTML or private JSON you normalize yourself |
| Pricing | 1 credit per request; 100 free credits on signup | Proxy, server, and engineering costs that scale with volume |
| Data coverage | Profiles, paginated post feeds, and video details | Whatever your scraper can reach before it breaks |
| Maintenance | SocialCrawl absorbs Kwai frontend changes upstream | Every Kwai update can silently break your pipeline |
