What is multi-shot in Kling 3.0?

Multi-shot lets one request return a connected sequence of up to five shots, each with its own prompt and duration (1–12s). Set multi_shots to true and provide multi_prompt. Kling 3.0 keeps characters and scenes consistent across the cuts — ideal for ads, storyboards, and short narratives.

How do I do image-to-video with Kling 3.0?

Include image_urls: the first entry is the start frame, and an optional second entry is the end frame (Kling 3.0 interpolates between them). URLs must be public HTTPS (no base64). Aspect ratio auto-adapts to your images, so the aspect_ratio field is ignored when frames are supplied.

How does Kling 3.0 pricing work?

Credit-based: 1 credit equals $0.001 USD. Kling 3.0 bills per second, dimensioned by mode (std 720p / pro 1080p / 4K) and whether audio is on. Total cost is the per-second rate times the video length; multi-shot bills the sum of shot durations. Failed and rejected requests are refunded. See the pricing card above for current rates.

What durations and aspect ratios does Kling 3.0 support?

Single-shot runs 3–15 seconds; multi-shot supports up to five shots of 1–12 seconds each. Aspect ratios are 16:9, 9:16, and 1:1 (default 16:9), auto-adapted when you supply frame images. Resolution is std 720p, pro 1080p, or 4K via the mode field.

Yes. You submit a Kling 3.0 task and receive a task_id, then poll /api/v1/tasks/:id until it is completed. This is the same task flow as every other reApi model, and the API returns a video URL you should mirror to your own storage if you need it long term.

Where is the full API reference for Kling 3.0?

The complete parameter list, modes, validation rules, error codes, and runnable cURL / Python / Node / Go examples for Kling 3.0 live at /docs/kling-3-0.

Is Kling 3.0 free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does Kling 3.0 require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get a Kling 3.0 API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

Kling 3.0 — Multi-Shot AI Video with Native Audio

Q: Does Kling 3.0 generate audio?

Yes. Turn sound on and Kling 3.0 generates synchronized audio with the video — multilingual dialogue with lip sync, dialects and accents, plus ambient sound. Audio tiers are priced above silent ones; you pay for sound only when you enable it.

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 unified API.

What is the Kling 3.0 API?

Kling 3.0 is Kuaishou's flagship video model, exposed on reAPI as one async endpoint covering text-to-video, image-to-video from a first frame with an optional last frame, and multi-shot sequences of up to 5 shots that each carry their own prompt and duration, plus up to 3 reusable elements built from 2–4 reference images. Every request renders 3–15 seconds in 16:9, 9:16, or 1:1 at std, pro, or 4K quality with optional native audio, billed per second of output at the rate for the tier you pick.

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 playground

Animate 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 for Kling 3.0

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, unified

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.
