Video generation from a text prompt, a start image, reference images, or a reference clip (Kling, Seedance, MiniMax H3, Wan, Veo, Grok Imagine, more), billed at the render's actual cost — from about half provider list price, never above list. Per-model length, resolution, and audio options; the call returns finished video URLs. Menu + prices: GET /api/v1/media/models (free).
