Quick comparison
Section titled “Quick comparison”| Model | Best for | Endpoint | Notes |
|---|---|---|---|
| Seedance 2.0 API | Cinematic text-to-video and image-to-video | /v1/videos | Strong general-purpose video model |
| Kling 3.0 API | Motion control and action-heavy clips | /v1/videos | Good for camera movement and physics |
| Wan 2.7 Image-to-Video API | Animating a still image | /v1/videos | Uses input_reference for source images |

Which video API should I choose?
Section titled “Which video API should I choose?”Choose Seedance 2.0 when you want a broad video model for cinematic prompts and image-to-video workflows. Choose Kling 3.0 when the motion itself is the hard part. Choose Wan 2.7 Image-to-Video when your source image should define the final clip.
The practical workflow is to test short clips first, compare output quality, then increase duration or resolution only after the prompt is stable.
Pricing
Section titled “Pricing”Current pricing is maintained on HiAPI Pricing. Video pricing usually depends on model, duration, resolution, and volume.
