What Is Seedance 2.0 API?

Seedance 2.0 API is a video generation API for creating AI videos from text prompts, images, and multimodal references. Through EvoLink.ai, developers can access the full Seedance 2.0 model family with one consistent API workflow:

create a generation task
receive a task ID immediately
poll task status or receive a callback
download the generated video result

This repository is designed for developers who want to:

understand Seedance 2.0 API price and model differences
rank for searches like Seedance 2.0 API, Seedance 2 API price, and Seedance API pricing
compare text-to-video, image-to-video, and reference-to-video modes
understand the difference between standard and fast models
copy production-ready request examples
estimate pricing before shipping

Supported Seedance 2.0 Models

Standard models

seedance-2.0-text-to-video
seedance-2.0-image-to-video
seedance-2.0-reference-to-video

Fast models

seedance-2.0-fast-text-to-video
seedance-2.0-fast-image-to-video
seedance-2.0-fast-reference-to-video

Quick Start

Create a Seedance 2.0 video task with a single API call:

curl --request POST \
  --url https://api.evolink.ai/v1/videos/generations \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "seedance-2.0-text-to-video",
    "prompt": "A cinematic aerial shot of a futuristic city at sunrise, soft clouds, reflective skyscrapers, smooth camera motion",
    "duration": 5,
    "quality": "720p",
    "aspect_ratio": "16:9",
    "generate_audio": true
  }'

Example response:

{
  "id": "task-unified-1774857405-abc123",
  "model": "seedance-2.0-text-to-video",
  "object": "video.generation.task",
  "status": "pending",
  "progress": 0,
  "type": "video"
}

Unified API Workflow

All Seedance 2.0 models use the same task-based workflow.

1. Create a generation task

POST https://api.evolink.ai/v1/videos/generations

2. Query task status

GET https://api.evolink.ai/v1/tasks/{task_id}

3. Retrieve results

When the task is completed, the response returns generated video URLs in the result payload.

4. Optional callback

You can pass callback_url in the create request if you want asynchronous notifications instead of polling only.

Model Comparison

Model	Input Type	Best For	Notes
`seedance-2.0-text-to-video`	text only	prompt-first video generation	supports optional web search
`seedance-2.0-image-to-video`	1-2 images	first-frame or first/last-frame animation	ideal for image animation workflows
`seedance-2.0-reference-to-video`	images, videos, audio, text	advanced multimodal generation and editing	best for editing, extension, and guided generation
`seedance-2.0-fast-text-to-video`	text only	faster prompt-based generation	same basic workflow as standard text model
`seedance-2.0-fast-image-to-video`	1-2 images	faster image animation	supports more image formats than the standard image model
`seedance-2.0-fast-reference-to-video`	images, videos, audio, text	faster multimodal generation	strong default for quick iteration

Core Request Parameters

Parameter	Type	Description
`model`	string	selects the Seedance 2.0 model
`prompt`	string	generation prompt, supported across all model families
`duration`	integer	output video duration, `4-15` seconds or `-1` for smart duration
`quality`	string	`480p` or `720p`
`aspect_ratio`	string	`16:9`, `9:16`, `1:1`, `4:3`, `3:4`, `21:9`, or `adaptive`

`callback_url`	string	optional HTTPS callback URL

Mode-by-Mode Guide

Text to Video

Use seedance-2.0-text-to-video or seedance-2.0-fast-text-to-video when you want to generate a video from prompt text only.

Key points:

no image, video, or audio inputs
supports optional model_params.web_search
good for concept generation and trend-aware prompts

Docs:

Text-to-Video Guide

Image to Video

Use seedance-2.0-image-to-video or seedance-2.0-fast-image-to-video when you want to animate one or two images.

Key points:

image_urls accepts 1-2 images
1 image = first-frame animation
2 images = first-frame to last-frame transition
useful for marketing, product visuals, social posts, and stylized motion clips

Docs:

Image-to-Video Guide

Reference to Video

Use seedance-2.0-reference-to-video or seedance-2.0-fast-reference-to-video for the most control.

Key points:

supports image_urls, video_urls, and audio_urls
can create new outputs from multimodal references
can extend, edit, or recompose videos
input reference videos affect billing

Docs:

Seedance 2.0 API Price

Output pricing

For text-to-video and image-to-video tasks, pricing is based on output duration:

cost = output video duration in seconds × resolution price

Resolution	Price
`480p`	4.63 credits / second
`720p`	10.00 credits / second

Reference video pricing

For reference-to-video tasks, input reference video duration is also billed:

cost = (input reference video duration + output video duration) × resolution price

Extra notes

audio generation has no extra charge
web_search costs 0.04 credits per actual search call
smart duration (-1) reserves 10 seconds first, then settles by actual output length
1 credit = 10,000 UC = ¥0.10

FAQ

Is Seedance 2.0 API synchronous?

No. Seedance 2.0 generation is asynchronous. You create a task first, then query task status later or use a callback URL.

What is the difference between standard and fast models?

Fast models follow the same request pattern but are positioned for quicker iteration. You should compare them by workflow needs, latency expectations, and output preference.

Can I generate video from only text?

Yes. Use seedance-2.0-text-to-video or seedance-2.0-fast-text-to-video.

Can I animate one image or create a start/end frame transition?

Yes. Use image-to-video. One image becomes the first frame. Two images become first and last frames.

Can I edit or extend an existing video?

Yes. Use reference-to-video with video_urls and a guiding prompt.

Does reference input affect billing?

Yes. Reference video duration is included in billing for reference-to-video tasks.

How long are result URLs valid?

Generated video URLs are valid for 24 hours. Save them promptly.
