Seedance 2.0 Mini

POSThttps://api.newportai.com/api/async/seedance_2.0

The Seedance 2.0 Mini Text To Video API is a cost-effective video generation model that generates videos directly from a text prompt at the lowest price point in the Seedance 2.0 series, supporting resolutions up to 720p, configurable aspect ratio and duration, and optional audio generation.

This API is ideal for quick iterations, previews, and budget-conscious projects that don't require the highest resolutions. It shares the same endpoint as Seedance 2.0 but with limited resolution options (480p and 720p).

  • Submit a POST request to the Seedance 2.0 Mini API to obtain a taskId.
  • Submit a POST request to the Polling API to retrieve the generated video results.
  • Configure a Callback URL to receive results automatically on completion.
