Authentication
string
required
All endpoints require Bearer Token authenticationGet API Key:Visit the API Key Management Page to get your API KeyAdd to request header:
Authorization: Bearer YOUR_API_KEY
Request Parameters
string
required
Video generation model name, fixed as
wan2.5-previewboolean
default:"false"
Whether 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)
string
Video content descriptionRequired for text-to-video (without
image_urls), optional but recommended for image-to-videoDescribe scenes, actions, styles in detail for better resultsExample: "Sunset coastal highway, cinematic shot"array<string>
Reference image URL array (only 1 image supported)Required for image-to-video mode, supports publicly accessible image URLs or Base64 encoding (
data:image/png;base64,...)Example: ["https://example.com/image.jpg"]The system automatically selects text-to-video or image-to-video mode based on whether
image_urls is included. Do not pass image_urls for text-to-video mode.string
Negative prompt, describes unwanted contentMaximum 500 charactersExample:
"blurry, low quality, distorted"string
default:"720p"
Video resolutionOptions:
480p- SD, supports size:16:9,9:16,1:1720p- HD (default), supports size:16:9,9:16,1:1,4:3,3:41080p- FHD, supports size:16:9,9:16,1:1,4:3,3:4
720pResolution directly affects pricing: 1080p > 720p > 480p.
480p only supports
16:9, 9:16, 1:1 ratios. Passing 4:3 or 3:4 will result in an error.integer
default:"5"
Video duration (seconds)Only supports:
5 or 10 secondsDefault: 5string
default:"16:9"
Aspect ratio, only effective for text-to-video (without
image_urls)Options depend on resolution:480p:16:9- Landscape (default)9:16- Portrait1:1- Square
16:9- Landscape (default)9:16- Portrait1:1- Square4:3- Landscape3:4- Portrait
16:9For image-to-video, the aspect ratio is determined by the input image. Do not pass
size, otherwise an error will be returned.integer
Random seed (≥0), specifying the same seed can reproduce similar resultsExample:
12345boolean
default:"true"
Whether to enable smart prompt rewritingSignificantly improves results for shorter prompts, but increases processing timeDefault:
trueboolean
default:"true"
Whether to automatically add audioWhen enabled, the system will generate matching audio for the videoDefault:
trueThis model only supports
audio=true. Setting to false for silent video is not supported.string
Custom audio URL (wav/mp3, 3-30 seconds, ≤ 15MB)If the audio is longer than the video duration, it will be automatically trimmed; if shorter, the remaining part will be silent
Audio file requirements:
- Format: wav, mp3
- Duration: 3-30 seconds
- Size: ≤ 15MB
boolean
default:"false"
Whether to add an “AI Generated” watermark (bottom right)Default:
falseResolution and Aspect Ratio Combinations
size and resolution combinations map to upstream pixel dimensions (only effective for text-to-video):
| Aspect Ratio | Description | 480p Size | 720p Size | 1080p Size |
|---|---|---|---|---|
16:9 | Landscape (default) | 832×480 | 1280×720 | 1920×1080 |
9:16 | Portrait | 480×832 | 720×1280 | 1080×1920 |
1:1 | Square | 624×624 | 960×960 | 1440×1440 |
4:3 | Landscape | - | 1088×832 | 1632×1248 |
3:4 | Portrait | - | 832×1088 | 1248×1632 |
480p only supports
16:9, 9:16, 1:1 ratios. Passing 4:3 or 3:4 will result in an error. 720p and 1080p support all 5 ratios.Response
