Kling API pricing
What one clip costs on Root, with sound on where the model has it. Prices are per clip, in dollars; 100 credits is $1. Failed runs are not charged.
| Model | 5 s, 720p | 10 s, 720p | 10 s, 1080p | 10 s, 4K |
|---|---|---|---|---|
| Kling 3.0 | $0.73 | $1.45 | $1.94 | $4.83 |
| Kling Omni | $0.65 | $1.29 | $1.61 | $4.83 |
| Kling 2.6 | $0.81 | up to $3.22 | up to $3.22 | — |
| Kling 2.5 Turbo | $0.25 | up to $3.22 | up to $3.22 | — |
A dash means that model can't make that clip. “Up to” means Kling bills that clip on what it reports after the run, so it can cost less. Kling 2.6 with sound always renders at 1080p, and its price includes that. The API and the app show the price before a run starts, and you're charged for what the run actually used. Compare every model
Which Kling model to use
| Model | Best for | Longest clip | Resolution | Sound |
|---|---|---|---|---|
| Kling 3.0 | Realistic motion and physics, and 4K output. | 10 s | 720p, 1080p, 4K | On or off |
| Kling Omni | Several reference images or elements in one shot, and longer takes. | 15 s | 720p, 1080p, 4K | On or off |
| Kling 2.6 | Realism and close prompt-following, with sound. | 10 s | 720p, 1080p | On or off |
| Kling 2.5 Turbo | Fast, silent takes while you iterate. | 10 s | 720p, 1080p | No |
We reach for Kling 3.0 when a shot needs believable weight and motion, and when another model refuses a subject it shouldn't.

The Kling API
Make an API key in Root under Settings, then API, and choose its daily spending limit. Then send a request:
curl https://root.film/api/v1/generations \
-H "Authorization: Bearer rfk_your_key" \
-H "Content-Type: application/json" \
-d '{"model":"kling-v3","project_id":"YOUR_PROJECT_ID",
"input":{"prompt":"a cyclist crossing a rainy bridge at night",
"duration_seconds":5,"resolution":"1080p"}}'- The finished clip is saved to the project you name, next to everything else in it.
- Pass an image with image_url to start from a frame, and last_frame_url to set where it ends.
- Send an Idempotency-Key header and a retry never charges twice.
- Read the API guide
