Kling 3.0 — Multi-Shot AI Video with Native Audio
Kling 3.0 is Kuaishou's flagship video model: write a prompt for text-to-video, animate a still with image-to-video, or direct a multi-shot sequence — each shot with its own prompt, duration, and camera work. It generates native multilingual audio with lip sync, up to 4K, and you call Kling 3.0 through reApi's OpenAI-compatible API.

What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Direct a multi-shot sequence
The headline upgrade in Kling 3.0 is multi-shot. Hand it up to five shots — each with its own prompt, duration, and camera direction — and Kling 3.0 returns one connected sequence with consistent characters and scenes across cuts. It is built for storyboards, ads, and short narratives where a single static clip is not enough, all from one request and one task ID.
Open the playgroundAnimate a still with image-to-video
Pass a start frame — and optionally an end frame — and Kling 3.0 animates the still into smooth motion, interpolating between the two when both are supplied. Aspect ratio auto-adapts to your images. It is the fastest way to turn a product shot, a character render, or a key frame into a moving clip without re-describing the whole scene in text.
Video with native audio
Turn on sound and Kling 3.0 generates synchronized audio with the video — multilingual dialogue with lip sync, dialects and accents, plus ambient sound — instead of a separate audio pass. Pair it with multi-shot prompts and you get talking characters across cuts, which makes Kling 3.0 a one-call tool for narrated shorts and dialogue scenes.

Why reAPI
Multi-shot storytelling in one call
Most video models give you a single clip. Kling 3.0 directs up to five shots — distinct prompts, durations, and camera moves — into one coherent sequence. You skip the stitch-and-sync busywork, and characters stay consistent across cuts through the same request to /api/v1/videos/generations.
Native audio, not a separate pass
Kling 3.0 generates synchronized audio with the picture — multilingual dialogue, lip sync, dialects, and ambient sound. Turn `sound` on and the clip comes back voiced. It is billed per second, with audio tiers priced above silent ones, so you pay for sound only when you ask for it.
Async-first, OpenAI-compatible
Submit a Kling 3.0 task, get a task_id back, poll until it completes. 1 credit equals $0.001 USD and you pay per second × tier, so cost is predictable. The JSON matches the OpenAI generations contract, so adding Kling 3.0 is a model-id change, not a new integration.
Kling 3.0 vs Veo 3
Both generate premium video with audio from one API. Kling 3.0 leans into multi-shot direction, multilingual audio, and flexible duration with per-second pricing. Here is how the two compare on publicly documented behavior.

Integrate Kling 3.0 in three steps
- step 01
Create an API key
Sign up at reApi and grab an API key. Free signup credits cover your first Kling 3.0 clips — enough to test text-to-video and image-to-video before you top up.
Open - step 02
Submit a generation
POST to /api/v1/videos/generations with model: kling-3-0, a prompt, and optional duration / aspect_ratio / mode / sound / image_urls. Kling 3.0 returns a task_id immediately.
Open - step 03
Poll the result
GET /api/v1/tasks/:id until status is completed. The Kling 3.0 response carries the video URL; mirror it to your own storage if you need it long term, since generated links expire.
