}Authentication
Authorization stringAll endpoints require Bearer Token authentication
Get API Key:
Visit the API Key Management Page to get your API Key
Add to request header:
Authorization: Bearer YOUR_API_KEYRequest Parameters
model stringVideo generation model name, fixed as wan2.6-i2v-flash
nsfw_check booleanWhether to run content moderation before submitting the video task.
true: useomni-moderation-latestto review prompts and input imagesfalseor omitted: do not send a moderation request, adding no moderation cost or latency (default)
image_urls string" required>
Reference image URL array (only 1 first-frame image supported)
Supports publicly accessible image URLs or Base64 encoding (data:image/png;base64,...)
Example: ["https://example.com/image.jpg"]
Image requirements:
* Format: JPEG, JPG, PNG (no transparency), BMP, WEBP
* Resolution: width/height range 240-8000 pixels
* Size: ≤ 10MB
prompt stringVideo content description
Optional but recommended for image-to-video, describes expected actions and effects
Clearly specify subject, action, camera and style for better results
Example: "The person in the image smiles and waves, camera slowly zooms in"
negative_prompt stringNegative prompt, describes unwanted content
Maximum 500 characters
Example: "blurry, low quality, distorted"
resolution stringVideo resolution
Options:
720p- HD1080p- FHD (default)
Default: 1080p
Resolution directly affects pricing, 1080p is more expensive than 720p. Aspect ratio is determined by the input image.
duration integerVideo duration (seconds)
Supported range: 2 to 15 seconds (integer)
Default: 5
audio booleanWhether to generate audio
Set to true: automatically generates matching background music/sound effects (default)
Set to false: outputs silent video
Default: true
Not supported when the model is wan2.6-i2v.
audio_url stringCustom audio URL (wav/mp3, 3-30 seconds, ≤ 15MB)
Lower priority than audio: ignored when audio=false
If audio is longer than video duration, it will be trimmed; if shorter, the remaining part will be silent
Audio file requirements:
* Format: wav, mp3
* Duration: 3-30 seconds
* Size: ≤ 15MB
prompt_extend booleanWhether to enable smart prompt rewriting
Significantly improves results for shorter prompts, but increases processing time
Default: true
shot_type stringShot type, requires prompt_extend=true
Options:
single- Single shot (default), outputs a continuous single-shot videomulti- Multi-shot, outputs a narrative video with multiple shot transitions
shot_type has higher priority than prompt. Even if the prompt mentions "multi-shot", setting single will still output a single shot.
seed integerRandom seed (≥0), specifying the same seed can reproduce similar results
Example: 12345
watermark booleanWhether to add an "AI Generated" watermark (bottom right)
Default: false
Audio Control
| Parameter Combination | Result |
|---|---|
No audio or audio_url |
Auto-generated audio (default) |
audio_url: "https://..." |
Use specified audio |
audio: false |
Silent video |
audio: false + audio_url: "..." |
Silent video (audio has higher priority) |
Response
code integerResponse status code, 200 on success
data arraystatus stringTask status, submitted on initial submission
task_id stringUnique task identifier for querying task status and results
