World-class video & image generation, at China pricing

Q: How is video generation billed?

Per second of generated video, at the resolution you choose. Seedance 2.0 runs from $0.067/s at 480p up to $1.00/s at 4K. You pay only for finished clips.

Q: Do the outputs have watermarks?

All image models carry a small visible AI-generated label applied upstream under China's content-labelling rules. Video varies by model: in our 4 August 2026 tests Seedance 2.0 and CogVideoX-Flash showed no visible label, while Hunyuan Video 1.5 is labelled. Text models are unaffected. See the watermark notice for the per-model table.

Seedance, Seedream, Hunyuan and Cog models through one API — billed per second and per image, at provider list price with no aggregator markup.

Quick Start

Two calls to your first generation

Video is an async task you poll; image is a synchronous request. Both use your single NovAI API key.

video — async task

# 1) create the task
curl https://aiapi-pro.com/v1/video/generations \
  -H "Authorization: Bearer $NOVAI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedance-2.0",
    "prompt": "A cat surfing a wave at sunset",
    "duration": 5
  }'

# 2) poll until status=succeeded, then read the video URL
curl https://aiapi-pro.com/v1/video/tasks/TASK_ID \
  -H "Authorization: Bearer $NOVAI_KEY"

image — synchronous

curl https://aiapi-pro.com/v1/images/generations \
  -H "Authorization: Bearer $NOVAI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedream-4.5",
    "prompt": "Product photo of a watch on marble",
    "n": 1
  }'

# response.data[].url holds your image
