Integrate this model with one task-based API flow

Seedance 2.0 Mini is the compact tier of ByteDance's Seedance 2.0 family - a video generation model built on the same unified multimodal audio-video joint generation architecture as its larger siblings, tuned for speed and cost. It accepts text, images, audio, and video inputs, references up to 12 files per generation, and delivers native synchronized audio with the picture. The examples below are rendered from Seedance 2.0 Mini, the current gateway base URL, and the selected public model contract.

Input mode
X-API-Key on every request
POST /api/v1/openapi/task
GET /api/v1/openapi/task/status/{task_id}
Async task workflow

Single code window

Switch language once. Each example already includes both the task creation request and the task status polling request.

Request and response JSON become the documentation

Keep the payload and task status envelope as the primary contract. Field descriptions, optionality, and enum hints now live inline as JSON comments.

Request Body

Caller payload

This is the request envelope accepted by the public gateway for the selected model contract.

Field comments and caller parameters come directly from the current item's model schema.
