Calling Methods

Create Task:
```
POST /aigc/videoGenAsync
```
→ Returns
```
{taskId}
```
Poll for Results:
```
POST /aigc/taskQuery
```
→ Pass in
```
{taskId}
```
→ Returns status and results
Python Script:
```
python scripts/aigc_videogen.py '<JSON parameters>'
```
(the script automatically handles creation + polling internally)

Asynchronous Process:

The script calls
```
/aigc/videoGenAsync
```
to create a task and obtains
```
taskId
```
Starts polling
```
/aigc/taskQuery
```
after waiting for 2 minutes, once every 10 seconds, with a maximum wait time of 20 minutes
Automatically downloads the video to the session
```
media/
```
directory upon success

Output Strategy (Default Script Behavior):

The script automatically downloads and saves the generated video to the session
```
media/
```
directory, and outputs a line
```
Saved full response: <path array>
```
to stdout.
The original API response is silently saved to
```
data/
```
, and its path is only prompted in stdout when there is no video product.

Data Reading Suggestion: Do NOT read the content of the saved video file. Directly provide the local path after

Saved full response:

to the user.

When the following exceptions occur, guide users to resolve them using references/onboarding.md:

Exception Scenarios

API Key Not Configured: The environment variable
```
LINKFOX_AGENT_API_KEY
```
or
```
LINKFOXAGENT_API_KEY
```
is not configured.
Response with 401 or 402 Status Code
Response Indicates Insufficient Points or Balance: Messages containing "insufficient points balance/insufficient billing/insufficient balance/quota exceeded/insufficient balance/package expired/need to recharge/please recharge" or similar meanings.

Usage Guidelines

Model Selection: Use
```
KLING
```
for general product videos; use
```
WAN
```
/
```
SEED
```
for longer durations.
First/Last Frames: Pass
```
imageUrl
```
(first frame, required) + optional
```
lastFrameImageUrl
```
(last frame). Supported models: KLING (Pro mode only) / WAN / SEED.
Duration Matching: Must pass a duration value supported by the model, otherwise an error will occur.
Prompt: Optional, within 2000 characters, describing the desired dynamic effects.

Examples

1. KLING — Product Display

json

{"imageUrl": "https://example.com/product.jpg", "videoType": "KLING", "videoTime": 10, "prompt": "Product display video"}

3. WAN Wanxiang — With Sound and Camera Movement

json

{"imageUrl": "https://example.com/scene.jpg", "videoType": "WAN", "videoTime": 15, "voice": true, "camera": "single"}

4. SEED — High Resolution

json

{"imageUrl": "https://example.com/scene.jpg", "videoType": "SEED", "videoTime": 10, "resolution": "1080p", "aspectRatio": "16:9"}

Display Rules

Only Display Saved Local Path: Tell users the local video path after
```
Saved full response:
```
, e.g., "Video saved to: xxx/a.mp4".
Do NOT read video files, do NOT display base64 content.
Do NOT directly provide the temporary URL returned by the original API to users (it is signed and will expire).

Limitations

Maximum prompt length is 2000 characters.
Generation time is relatively long, usually 100-600 seconds. The script automatically polls, with a timeout of 20 minutes.
KLING's last frame image is only supported in Pro mode.
This interface only supports single image/first-last frame mode. For multiple reference images, use
```
linkfox-aigc-videogen-multi
```
.
No retries on failure (only one attempt).

Not Applicable Scenarios

Not applicable for:

Video generation with multiple reference images → Use
```
linkfox-aigc-videogen-multi
```
Image generation → Use
```
linkfox-aigc-imagegen
```
Text generation → Use
```
linkfox-aigc-textgen
