HiAPI HappyHorse 1.0 Video

Use this skill when the user wants text-to-video generation through HiAPI's happyhorse-1-0 model.

Requirements

• Node.js 18 or newer.
• HIAPI_API_KEY must be set in the environment.
• HIAPI_BASE_URL is optional and defaults to https://api.hiapi.ai.

Important links:

• Get API key: https://www.hiapi.ai/en/register
• Pricing: https://www.hiapi.ai/en/pricing
• Docs: https://docs.hiapi.ai

Never invent a video result. If the API call fails, report the status code, compact error message, and the next action from the Error Guidance section.

Generate A Video

Run:

node scripts/hiapi-happyhorse-1-video.mjs \
  --prompt "A wuxia swordswoman leaps across temple rooftops at dusk, silk robes flowing in the wind" \
  --seconds 5 \
  --resolution 1080p \
  --ratio 16:9

Supported durations:

• any integer from 3 to 15

Supported resolutions:

• 720p
• 1080p

Supported aspect ratios (--ratio, legacy alias --size):

• 16:9
• 9:16
• 1:1
• 4:3
• 3:4

Optional seed:

• integer from 0 to 2147483647
• omit it when the user does not request reproducibility

The script creates a video task, polls until it finishes, downloads the video to outputs/ when possible, and prints JSON with the saved file path or remote URL.

API Contract

This skill calls:

POST /v1/tasks
GET /v1/tasks/{taskId}

with:

{
  "model": "happyhorse-1-0",
  "input": {
    "prompt": "...",
    "duration": 5,
    "resolution": "1080p",
    "aspect_ratio": "16:9",
    "seed": 12345
  }
}

HappyHorse 1.0 is text-to-video. Do not send image inputs to this model. The CLI maps --seconds to input.duration and --ratio (legacy alias --size) to input.aspect_ratio. Use --seed only when the user requests reproducibility.

For details, read references/api.md and references/output.md.

Check Configuration

Run:

node scripts/check-config.mjs

Use --live only when you want to verify that the configured key can reach the HiAPI pricing endpoint.

Error Guidance

• Missing HIAPI_API_KEY: tell the user to create or copy a key from https://www.hiapi.ai/en/register and export it.
• HTTP 401 or 403: tell the user to verify the HiAPI API key.
• HTTP 402, HTTP 403 with quota text, insufficient balance, credits, quota, or payment errors: tell the user to add credits or check billing at https://www.hiapi.ai/en/dashboard and review pricing at https://www.hiapi.ai/en/pricing.
• HTTP 400: tell the user to check duration, resolution, aspect_ratio, and seed.
• HTTP 429: tell the user to wait and retry or reduce concurrent video generations.
• Task failure: ask the user to try a clearer prompt.
• Timeout: explain that video generation may still be running and the user can retry later.
• Optional skill update notice: tell the user the printed update command can be run later.
• Required skill update notice: tell the user the printed update command must be run before using this skill again.
