ccapi-ai MiniMax H3 Family Video Generation API
Generate 5–15 second videos through the unified CCAPI task flow. H3 provides text-to-video, image-to-video, and reference-to-video. Reference-to-video accepts image, video, and audio inputs and also covers video-to-video and video editing. H3 Max Turbo provides text-to-video and image-to-video. ## Models | Model | Resolutions | Input | |---|---|---| | `minimax/h3/text-to-video` | 480P / 768P / 2K / 4K | Text | | `minimax/h3/image-to-video` | 480P / 768P / 2K / 4K | Opening image, optional ending image | | `minimax/h3/reference-to-video` | 480P / 768P / 2K / 4K | Up to 9 images, 3 videos, and 3 audio files | | `minimax/h3-max-turbo/text-to-video` | 480P / 768P / 1080P | Text | | `minimax/h3-max-turbo/image-to-video` | 480P / 768P / 1080P | Opening image, optional ending image | ## Billing Billing is based on generated seconds and output resolution. At 768P, a 5-second H3 Max Turbo video costs $0.24 and a 5-second H3 video costs $0.36. The first five reference images are included for H3 reference-to-video; each additional image costs $0.096. Failed tasks are not charged.

description: 'Unified OpenAI-compatible video generation endpoint. Choose the matching oneOf request schema branch (e.g. Gemini Video / Grok Imagine Video / Seedance 2.5 / Seedance 2.0) based on the `model` value.
Scalar may list this operation under multiple video model groups, but they all point to the same real callable route: `POST /v1/videos`. The response returns a `task_id`; poll `GET /v1/videos/{task_id}` for the result.
Requests using Seedance official public assets are subject to enforced limits: New users: 3 requests per day. Paid users: 20 requests per day, 1 RPM, and 1 concurrent task. HTTP 429 responses include `Retry-After`. Repeated upstream real-person, copyright, or content-safety rejections automatically suspend official-asset generation for the account; systemic failures temporarily open a circuit breaker.'
