Why Choose ModelFold for Kling O3 API
Text, Image, Reference and Transformation Models on One Endpoint
kling-3.0-omni/text-to-video, kling-3.0-omni/image-to-video, kling-3.0-omni/reference-to-video and kling-3.0-omni/transformation all run on POST https://ai.modelfold.online/v1/videos/generations with one ModelFold API key. Text-to-video outputs up to 4K and from 3 to 15 seconds; the full parameter list is in the Playground and the API section on this page. Pricing for each resolution is shown in the pricing line above and in the rate card of the API section.
Custom Shots or Model-Planned Shots, Not Both
Custom multi-shot takes up to 6 shots, each 1 to 12 seconds and 15 seconds in total, while intelligent shot planning lets the model split the video itself. The two switches cannot both be on, and shot prompts are only accepted when custom multi-shot is enabled.
Aspect Ratio and Audio Rules by Mode
Single-shot image-to-video requires the auto aspect ratio, and transformation with a video alone accepts only auto. Set audio explicitly on each request. Audio is priced separately in the rate card; when a video is provided, no audio is generated, and transformation is billed on the length of the input video. New ModelFold users receive 80 free credits for testing.
