API usage example

The UniAll AI video generation endpoint is asynchronous:

```bash curl -X POST "https://api.uniall.ai/v1/videos/generations" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "happy-horse-1080p", "generation_mode": "text_to_video", "prompt": "A cinematic product reveal, soft studio lighting, smooth camera movement.", "duration": 5, "aspect_ratio": "16:9", "resolution": "1080p", "video_count": 1 }' ```

For image-to-video, include `image_url`. For multi-reference workflows, include `reference_image_urls`.

Pricing angle

Happy Horse 1080p is billed per second of generated video. The listed UniAll AI user price for the 1080p variant is **$0.1904 per second**. A 5-second generation is therefore estimated at about **$0.952** before any account-specific discounts, taxes, or promotional credits.

The 720p variant is priced lower at **$0.0952 per second**, making it useful for prompt testing and iteration. For production-quality assets, 1080p offers better output resolution at a higher per-second cost.

Failed generations are eligible for refund handling according to the model configuration. Automatic retry is not enabled by default, so production systems should handle task status checks and retry logic where appropriate.

Who should use Happy Horse 1080p API?

Happy Horse 1080p is suitable for developers, agencies, ecommerce teams, creator tools, and SaaS platforms that need reliable short-video generation in an automated workflow. It is especially useful when teams want to connect AI video creation to internal tools, ad pipelines, content calendars, or customer-facing applications.

If cost is the main constraint, start with 720p for drafts. If output quality and final delivery matter more, use `happy-horse-1080p`.
