Authentication
authorization string required
All APIs require authentication via Bearer Token.
Get API Key:
Visit API Key Management Page to get your API Key.
Usage:
Add to request header:
Authorization: Bearer YOUR_API_KEY
Parameters
model string required
Model ID to use for the request
Value: minimax_hailuo_02_i2v
last_frame_image string
Use specified image as the video’s ending frame. Supports public URL or Base64 encoded Data URL (data:image/jpeg;base64,…)
Image requirements:
Format: JPG, JPEG, PNG, WebP
Size: Less than 20MB
Dimensions: Short side greater than 300px, aspect ratio between 2:5 and 5:2
⚠️ Video dimensions follow the first frame image. When the first and last frame images have different dimensions, the model will crop the last frame image based on the first frame.
prompt string
Text description for video generation, maximum 2000 characters. Supports camera movement control using [instruction] syntax for precise camera control.
Supported 15 camera instructions:
Pan: [pan left], [pan right]
Tilt: [tilt left], [tilt right]
Push/Pull: [push in], [pull back]
Rise/Lower: [rise], [lower]
Up/Down tilt: [tilt up], [tilt down]
Zoom: [zoom in], [zoom out]
Other: [shake], [follow], [static]
Usage rules:
Combined movements: Multiple instructions within the same [] will take effect simultaneously, e.g. [tilt left, rise], recommend no more than 3 combined
Sequential movements: Instructions appearing in sequence in the prompt will take effect in order, e.g. ”…[push in], then…[pull back]“
Natural language: Camera movements can also be described in natural language, but standard instructions provide more accurate responses
first_frame_image string required
Use specified image as the video’s starting frame. Supports public URL or Base64 encoded Data URL (data:image/jpeg;base64,…)
Image requirements:
Format: JPG, JPEG, PNG, WebP
Size: Less than 20MB
Dimensions: Short side greater than 300px, aspect ratio between 2:5 and 5:2
⚠️ Video dimensions follow the first frame image.
prompt_optimizer boolean
Whether to automatically optimize prompt, default is true. Set to false for more precise control
Default: true
duration integer
Video duration in seconds. Available values depend on resolution:
| Resolution | Available duration |
|---|---|
| 768P | 6 or 10 |
| 1080P | 6 |
Default: 6
resolution enum<string>
Video resolution
Image-to-video:
| Duration | Available resolution |
|---|---|
| 6s | 512P, 768P (default), 1080P |
| 10s | 512P, 768P (default) |
Start-end frame generation:
| Duration | Available resolution |
|---|---|
| 6s | 768P (default), 1080P |
| 10s | 768P |
Options: 512P, 768P, 1080P
callback_url string
Callback URL for receiving task status update notifications. Supports configuring callbacks via the callback_url parameter to receive asynchronous notifications of task status updates
aigc_watermark boolean
Whether to add watermark to the generated video
Default: false
Polling
Since result generation takes time, you need to poll the task status after creating the task.
The initial response only returns information such as the task ID and initial status. The final result must be obtained by polling the task status endpoint using the task ID.
See the examples on the right for polling requests and responses.
