Frequently asked

What is the cost of Happy Horse 1.1 Text to Video?

Happy Horse 1.1 Text to Video costs $0.14/sec at 720p (default) or $0.18/sec at 1080p on muapi — cheaper per-second than Happy Horse 1.0 at both resolutions. A 5-second 720p clip costs $0.70; the same clip at 1080p costs $0.90.

How is 1.1 different from Happy Horse 1.0?

1.1 is a newer generation with improved reliability (automatic fallback to a secondary provider if the primary submit fails) and lower per-second pricing at both resolutions.

How do I choose the resolution?

Pass `resolution: "720p"` (default) or `resolution: "1080p"` in your request body — both are served by the same endpoint.

Can I request multiple videos with the same prompt?

Yes — submit the same prompt multiple times to get different creative interpretations.

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.
