Authorizations

Authorization · string · header · required

Pass Authorization: Bearer <token> in the request header.

Headers

Content-Type · enum<string> · default: application/json · required

Media type of the request body. Set to application/json.

Available options: application/json

Body

application/json

model · enum<string> · required

Model name. Currently available: MiniMax-H3, MiniMax-H3-Max.

• MiniMax-H3: supports text-to-video, image-to-video (first / last frame), and multimodal reference-to-video; resolution 768P / 2K, duration 4 ~ 15 seconds.
• MiniMax-H3-Max: fast generation version. Supports text-to-video and image-to-video (first / last frame) only; multimodal references (reference image / reference video / reference audio) are not supported; resolution 480P / 768P, 2K is not supported; duration 5 ~ 15 seconds.

Available options: MiniMax-H3, MiniMax-H3-Max

content · object[] · required

Multimodal input content array describing the information used to generate the video. Each element is distinguished by type (text / image_url / video_url / audio_url) and can be annotated with a role.

Each request must contain a non-empty text item (prompt is required); omission will return a parameter error. Supported input combinations (corresponding to different generation scenarios):

Text-to-video: a single text element only.

resolution · enum<string> · default: 768P · required

Video resolution. Available values: 480P, 768P, 2K.

• MiniMax-H3: supports 768P and 2K.
• MiniMax-H3-Max: supports 480P and 768P (default 768P, 2K is not supported).

Available options: 480P, 768P, 2K

duration · enum<integer> · default: 5 · required

Video duration in seconds. Required, integer.

• MiniMax-H3: 4 ~ 15 seconds.
• MiniMax-H3-Max: 5 ~ 15 seconds (4 seconds is not supported).

Available options: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

ratio · enum<string>

Output video aspect ratio, default adaptive (automatically selects the most suitable aspect ratio based on input; the actual ratio can be retrieved from the ratio field in the query API).

Text-to-video (t2va, content contains only text): ratio is required and cannot be adaptive; available values: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16.

Available options: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16

callback_url · string

Callback notification URL for task status changes. After configuration, the MiniMax server will first send a verification request containing a challenge field (must return the challenge value unchanged within 3 seconds to complete verification). Once verified, whenever the task status changes, a POST push will be sent to this URL, with the push body structure matching the query task API response.

Callback status values: queued, running, succeeded, failed, cancelled.

Response

200 - application/json

Returns task_id upon successful creation. Use this task_id to call the query task API to retrieve task status and results.
