mediaio-ai-dance-video-generator（Mediaio AI 舞蹈视频生成器）

Media.io AI Dance Video Generator Skill

Overview

This skill calls Media.io OpenAPI to run dance video generation using model code effects-video-babydance. The API is asynchronous:

1. Submit generation request and get task_id.
2. Poll task result endpoint until the task is finished.

When To Use

• The user wants a dance animation generated from an image and a driving video.
• The user can provide source URLs reachable by Media.io servers.
• The user wants task-based generation with polling.

When Not To Use

• The user asks for local file upload only (this API expects URL input).
• The user asks for non-Media.io providers.
• The user asks for real-time synchronous video output in one call.

Requirements

Environment Variables

Base Headers

• Content-Type: application/json
• X-API-KEY: $MEDIAIO_API_KEY

Supported Endpoints

1) Query Credits

• Method: POST
• Endpoint: https://openapi.media.io/user/credits
• Body: {}
• Purpose: check available credits before generation.

2) Create Dance Video Task

• Method: POST
• Endpoint: https://openapi.media.io/generation/effects/effects-video-babydance
• Body:

{
	"data": {
		"image": "https://example.com/portrait.jpg",
		"video": "https://example.com/dance.mp4"
	}
}

• Required fields:

- data.image (string URL) - data.video (string URL)

3) Query Task Result

• Method: POST
• Endpoint: https://openapi.media.io/generation/result/{task_id}
• Body: {}
• Path parameter:

- task_id (string, required)

Request and Response Contract

Common Success Envelope

{
	"code": 0,
	"msg": "",
	"data": {},
	"trace_id": "..."
}

Create Task Response

• On success, data.task_id is returned.

Task Result Response

• data.status can be one of the following values:

- waiting: queued - processing: running - completed: completed successfully - failed: failed - timeout: timed out

• data.reason: provides additional context (e.g., success or error message)
• When status is completed:

- data.result is an array of output objects with generated URLs - Each result object contains val (internal path), preview (public HTTPS URL), and status (completion status)

Standard Invocation Flow

1. Call user/credits to verify balance.
2. Call effects-video-babydance with data.image and data.video.
3. Extract task_id.
4. Poll generation/result/{task_id} every 3 to 5 seconds.
5. Stop when status is completed or failed.
6. Return output URLs from data.result when completed.

cURL Examples

Query Credits

curl --request POST \
	--url https://openapi.media.io/user/credits \
	--header 'Content-Type: application/json' \
	--header "X-API-KEY: $MEDIAIO_API_KEY" \
	--data '{}'

Create Dance Video Task

curl --request POST \
	--url https://openapi.media.io/generation/effects/effects-video-babydance \
	--header 'Content-Type: application/json' \
	--header "X-API-KEY: $MEDIAIO_API_KEY" \
	--data '{
	"data": {
		"image": "https://example.com/portrait.jpg",
		"video": "https://example.com/dance.mp4"
	}
}'

Query Task Result

curl --request POST \
	--url https://openapi.media.io/generation/result/<task_id> \
	--header 'Content-Type: application/json' \
	--header "X-API-KEY: $MEDIAIO_API_KEY" \
	--data '{}'

Successful Response Example

{
	"code": 0,
	"msg": "",
	"data": {
		"task_id": "effect-3dbdb8ca-1f5e-4b1c-9c08-43a4a9bb8e2b",
		"status": "completed",
		"reason": "success",
		"result": [
			{
				"val": "aicloudtmp/550160908/3/202603/1/combo_tm_alg-20260317165022-802800-60eb3-dwt.mp4",
				"preview": "https://url_to_generated_image.png",
				"status": "completed"
			}
		]
	},
	"trace_id": "d63f54745ea24238bc6be4e6fe3d4937"
}

Response fields when status is completed:

• data.task_id: unique task identifier
• data.status: completed indicates successful completion
• data.reason: success indicates no error occurred
• data.result: array of output objects, each containing:

- val: internal file path of the generated asset - preview: publicly accessible HTTPS URL for the generated asset - status: completed for each result item

Error Handling Guidance

• Treat code != 0 as failure.
• Typical authentication errors:

- 374004: not authenticated. Apply for an APP KEY at https://developer.media.io/.

• Typical request validation error:

- 490000: params error

• Typical billing/credits error:

- 490505: insufficient credits. Recharge before invoking generation APIs.

• Always include trace_id in logs for troubleshooting.

Agent Behavior Requirements

• Validate that input contains non-empty image and video URLs before calling the create endpoint.
• Do not claim immediate output after task creation; always poll by task_id.
• If credits are insufficient, return a clear message and stop instead of retry loops.
• Avoid exposing raw API keys in logs or responses.

Safety and Compliance Notes

• Only process user-provided or user-authorized media.
• Do not imply identity verification or biometric certainty from generated videos.
• Generated output is synthetic media and should be presented as edited content.
