Implementation Guide

Developer documentation

Write a detailed text prompt describing the video scene you want to generate (e.g., 'a dragon flying over snowy mountains at sunset, cinematic style').
Set resolution to "720p" (cheaper, default) or "1080p" (premium output) depending on whether you're drafting or finalizing.
Select your desired aspect ratio and duration (3-15 seconds).
Submit your request to muapi—Happy Horse 1.0 will interpret your prompt and generate an expressive, stylized video at the selected resolution.
Download the generated video and review. Refine your prompt or bump the resolution if you want a higher-quality pass.

Common Questions

Frequently asked

What is the cost of Happy Horse 1.0 Text to Video?

Happy Horse 1.0 Text to Video costs $0.18/sec at 720p (the default) or $0.36/sec at 1080p on muapi. A 5-second 720p clip costs $0.90; the same clip at 1080p costs $1.80.

How do I choose the resolution?

Pass `resolution: "720p"` (default, cheaper) or `resolution: "1080p"` (premium output, 2x the rate) in your request body. Both are served by the same endpoint.

How does style and tone get conveyed in a text-only prompt?

Include descriptive style keywords in your prompt (e.g., 'cinematic', 'whimsical', 'surreal', 'photorealistic', 'animated', 'neon'). The model interprets these terms to shape the visual tone and artistic treatment of your video.

Can I request multiple videos with the same prompt?

Yes — submit the same prompt multiple times to get different creative interpretations, since generation includes natural variation between runs.

What happened to the dedicated 720p/1080p endpoints?

They still work exactly as before, unchanged, for existing integrations. This unified endpoint is the new recommended way to access both resolutions through one integration.
