Why developers choose the Seedance API

Designed for engineering teams requiring reliable 1080p output, low latency, and seamless integration into existing content pipelines.

Efficiency Meets Quality

The Seedance API balances speed and fidelity, allowing you to generate 2–12s HD clips in seconds. It bridges the gap between lightweight draft models and slow, expensive pro models.

Native Aspect Ratio Support

Define output dimensions programmatically. The API supports 16:9, 1:1, 9:16, and custom ratios, ensuring content is platform-ready for TikTok, Reels, or YouTube without post-processing.

Scalable Infrastructure

Built on EvoLink's robust architecture, the Seedance API offers operational headroom with ~600 RPM per account, ensuring your batch jobs run smoothly without throttling.

How to integrate the Seedance API

Go from zero to generated video in three simple API calls using the EvoLink unified SDK.

1

Step 1 — Configure API Endpoint

Select the text-to-video or image-to-video endpoint. Define your video duration (2–12s) and aspect ratio parameters in the request header.

2

Step 2 — Send Generation Payload

Submit your prompt with specific camera instructions. For I2V, pass your reference image URL to the Seedance API to ensure visual continuity.

3

Step 3 — Retrieve & Scale

Receive the generated 1080p video URL via webhook or polling. Iterate programmatically to refine motion or scale up production batches.

Seedance API Frequently Asked Questions

The Seedance API (Pro Fast edition) is optimized for developers needing speed and efficiency. It retains 1080p quality and camera controls but utilizes an optimized inference engine to render videos 3x faster and at ~60% lower cost than the standard Seedance Pro API.
Authentication is handled via the EvoLink unified gateway. You will need to pass your unique API Key in the header of each HTTP request. Refer to the developer documentation for specific header formats.
The API accepts JSON payloads containing text prompts for T2V, and image URLs combined with optional text prompts for I2V (Image-to-Video). You can also include specific parameters for camera movement and aspect ratios.
Yes, to ensure stability, the default quota is approximately 600 Requests Per Minute (RPM) with a concurrency limit of 10 tasks per model version. Enterprise plans can request higher limits.
Currently, the Seedance API focuses exclusively on high-quality visual generation and outputs silent video files. Audio generation should be handled by a separate TTS or music generation API service.
While 'Pro Fast' is significantly quicker than standard models, video generation is compute-intensive. It is best suited for near-real-time or asynchronous workflows rather than instant real-time interaction.
