Kling 3.0 Turbo — Fast Text-to-Video & Image-to-Video
Kling 3.0 Turbo is Kuaishou's fast Kling video model: write a prompt for text-to-video, or drop in a first frame for image-to-video, and Kling 3.0 Turbo returns a 720p or 1080p clip in seconds. You call Kling 3.0 Turbo through reApi's OpenAI-compatible API and pay per second.

What you can build with this model
Real-world workflows and production use cases you can build and ship with this model.
Prompt to clip in seconds
Kling 3.0 Turbo is built for speed: hand it a prompt and it returns a finished clip fast, so you can iterate on motion, framing, and pacing without long waits. It reads cinematic language for camera moves and action, which makes it a fast text-to-video engine for social posts, ad variants, and rapid concept tests — all from one request and one task ID.
Open the playgroundAnimate a still with image-to-video
Pass a first frame and Kling 3.0 Turbo animates the still into smooth motion. Aspect ratio follows the frame, so a product shot, a character render, or a key frame turns into a moving clip without re-describing the whole scene in text. It is the fastest way to bring an existing image to life.
Iterate at 720p, finish at 1080p
Because Kling 3.0 Turbo bills per second by resolution, you can draft at 720p to explore ideas cheaply, then re-run the winner at 1080p for delivery. Same prompt, same API call, one parameter change. It keeps the cost predictable while you move from rough cut to final clip.

Why reAPI
Turbo speed without a new integration
Kling 3.0 Turbo is the fast tier of the Kling family — it returns clips quickly so you can iterate in a tight loop. It runs on the same OpenAI-compatible /api/v1/videos/generations endpoint, so adding Kling 3.0 Turbo is a model-id change, not a new integration.
Text-to-video and image-to-video in one model
Send a prompt for text-to-video, or add a first frame for image-to-video — Kling 3.0 Turbo picks the mode from your inputs. No separate endpoints, no mode flag: the same call covers both paths at 720p or 1080p.
Async-first, pay per second
Submit a Kling 3.0 Turbo task, get a task_id back, poll until it completes. 1 credit equals $0.001 USD and you pay per second by resolution, so cost is predictable. Failed and rejected requests are refunded.
Kling 3.0 Turbo vs Runway Gen-3
Both generate video fast from one API. Kling 3.0 Turbo leans into per-second pricing, a simple text-to-video and image-to-video surface, and 720p / 1080p output. Here is how the two compare on publicly documented behavior.

Integrate Kling 3.0 Turbo 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 Turbo 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-turbo, a prompt, and optional first_frame_image / resolution / duration / aspect_ratio. Kling 3.0 Turbo returns a task_id immediately.
Open - step 03
Poll the result
GET /api/v1/tasks/:id until status is completed. The Kling 3.0 Turbo response carries the video URL; mirror it to your own storage if you need it long term, since generated links expire.
