Frequently asked questions

What does the Kwai Post API do?

The Kwai Post API lets you fetch full metadata and engagement stats from a public Kwai video using one GET request to /v1/kwai/post. It returns clean JSON — no OAuth or scraping setup required.

How many credits does the Kwai Post API cost?

Each successful call costs 17 credits. Responses are cached for 24 hours, and cached results cost 0 credits. Failed or empty results are never charged.

Do I need a Kwai API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, and Rumble. We handle proxies, rate limits, retries, and authentication for you.

Is the Kwai Post API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON, automatic retries, and a shared 24-hour cache. Use it for RAG pipelines, analytics, monitoring, and content automation.
