REST

Unified API entry point

Covering the key actions of video production

No need to piece together workflows across multiple vendor APIs—HappyHorse consolidates common video generation and editing modes into a unified request structure.

✍️

Text-to-video

Enter shot descriptions, scenes, and actions to quickly generate short video prototypes.

🖼️

First-frame image-to-video

Use a fixed first frame to control composition and bring static visual assets to life naturally.

🎭

Reference image-to-video

Use multiple reference images to constrain characters, props, styles, and visual elements.

✂️

Video editing

Use input videos and reference images for style transfer, outfit changes, and local replacement.

Submit a video task with one request

Use async to immediately return a task ID, then query the result through /happyhorse/tasks; if callback_url is provided, the final result will be pushed to your service after the task is completed.

Choose an action

Text-to-video, image-to-video, reference images, and editing all use the same endpoint.

Provide assets

Images and videos must be publicly accessible URLs; using Ace Data Cloud CDN is recommended.

Query results

Use task_id to obtain the final CDN video URL, duration, and resolution.

Three scenarios for real product integration

From marketing assets to content tools, HappyHorse is better suited as a reliable video capability module rather than a one-time toy.

Brand short film prototypes

Quickly generate short clips of products, characters, and scenes from text and first frames to validate visual direction.

Character and prop consistency

Use multiple reference images to lock in characters, clothing, props, and visual style.

Video post-production editing

Apply style transfer, local replacement, and audio preservation strategies to existing clips.

Launch video capabilities in three steps

Reuse Ace Data Cloud's unified authentication, billing, task, and callback model for a clear and controllable integration path.

Request a Token

Create an application in the console to obtain a unified Bearer Token.

Submit a task

Provide prompt, image_url, image_urls, or video_url according to the action.

Retrieve results

Get a downloadable CDN video URL through the task API or callback.

Why Use a Unified API

Consolidate model calls, task polling, CDN transfer, error classification, and billing records on the platform side.

Capability	Ace Data Cloud HappyHorse	Some Others
Multiple video actions	Unified `/happyhorse/videos`	Multiple APIs to combine yourself
Result files	Automatic CDN transfer	Temporary URLs commonly expire
Billing	Recorded by actual seconds	Requires building your own usage ledger
Failure handling	Structured error codes	Upstream error formats are inconsistent

Choose a Model by Task

1.1 models are prioritized for generation tasks; video editing currently uses 1.0 video-edit.

T2V

happyhorse-1.1-t2v

The default text-to-video model, suitable for generating short videos from scripts and shot descriptions.

I2V

happyhorse-1.1-i2v

Controls composition and visual tone with a first-frame image, suitable for animating product and character images.

R2V

happyhorse-1.1-r2v

Uses multiple reference images to constrain characters and props, suitable for scenarios with higher consistency requirements.

EDIT

happyhorse-1.0-video-edit

Edits based on input video, with the option to preserve the original audio.

Clear Per-Second Pricing

Failed tasks are not billed; video editing is billed based on the combined input and output duration returned by the upstream provider.

Frequently Asked Questions

The parameters, assets, and billing questions you are most likely to care about before launch.

What input assets does HappyHorse support?

Text-to-video only requires a prompt; first-frame image-to-video requires image_url; reference image-to-video requires 1–9 image_urls; video editing requires video_url, with an optional 0–5 reference images.

Will the returned video URL expire?

Ace Data Cloud transfers upstream results to the platform CDN, and the CDN URLs used in the documentation and API responses are accessible.

How should long-running generation be handled?

It is recommended to use async or callback_url. The API will first return a task_id, which you can actively query through /happyhorse/tasks or wait for a callback.

Are failed tasks charged?

No. Only tasks that complete successfully and have recorded results are billed based on duration and resolution.
