중국 본토 사용자 안내: 중국 본토 사용자는 https://toapis.cn 를 API 엔드포인트(Base URL)로 사용해 주세요. 본 문서의 예시에서 https://toapis.com 을 https://toapis.cn 로 바꿔 주세요.

Supports seedance-2, seedance-2-fast, and seedance-2-mini
Supports text-to-video, first-frame / first-last-frame image-to-video, and multimodal reference-to-video; seedance-2-mini also supports frame roles and the audio generation switch
Supports combined image, video, and audio references; seedance-2-mini allows up to 9 images, 3 videos, and 3 audios
Async task workflow: the submit API returns generation.task, and the completed result is fetched from the task status API

Authorizations

string

필수

All requests require Bearer Token authentication.Get your API Key from the API Key Management Page.

Authorization: Bearer YOUR_API_KEY

Body

string

기본값:"seedance-2"

필수

Video generation model name.Available models:

seedance-2 - Standard version for higher quality output and the broader Seedance 2 workflow
seedance-2-fast - Faster version for previews and lower-latency iteration
seedance-2-mini - Lightweight version for lower-cost drafts and multimodal reference workflows, currently fixed to 1 result per request

string

Video prompt.We recommend clearly describing the scene, camera motion, subject action, style, and audio mood.

string

Your business-side ID, such as an order number or internal job ID. Once submitted, it is stored with the task and can be used later for status lookup: GET /v1/videos/generations/{client_business_id}.metadata.client_business_id is also accepted, but the top-level field is recommended.

boolean

기본값:false

선택 사항이며 기본값은 false입니다. 미디어 입력이 있는 요청에 사용합니다. true이면 기존 규칙으로 채널을 선택합니다. 소재 라이브러리를 지원하는 채널은 소재 준비와 심사를 자동 처리하고 필요한 심사가 모두 통과한 뒤 생성을 제출합니다. 다른 채널은 비공개 소재 심사를 건너뛰고 기존 미디어 처리를 유지합니다. HTTP는 먼저 동영상 작업을 반환합니다. 심사할 이미지는 URL과 Base64, 동영상과 오디오는 HTTP(S)를 지원하며 모델의 기존 형식 제한도 적용됩니다. 새 모드의 asset://는 HTTP 400을 반환합니다. 생략하거나 false로 설정하면 기존 동작을 유지합니다.예시, 입력 우선순위, 재사용 규칙은 요청 시 소재 심사를 참고하세요.

integer

기본값:0

Video duration in seconds.Rules:

seedance-2: 4-15
seedance-2-fast: 4-15
seedance-2-mini: 4-15
0: auto duration (seedance-2 / seedance-2-fast only)
-1: auto duration (seedance-2 / seedance-2-fast only)

string

Video aspect ratio.Options:

21:9
16:9
4:3
1:1
3:4
9:16
adaptive

adaptive lets the upstream choose an appropriate ratio from the input media.

string[]

Compatibility image URL array.We recommend using image_with_roles instead so you can explicitly mark first_frame, last_frame, or reference_image.

Do not use image_urls together with image_with_roles.
For new integrations, use image_with_roles to explicitly mark how each image should be used.

array

Image list with explicit roles.Supported patterns:

seedance-2 / seedance-2-fast / seedance-2-mini
- first_frame for first-frame image-to-video
- first_frame + last_frame for first-last-frame video generation
- reference_image for multimodal reference generation

표시 Field details

string

필수

Image URL, Base64 data, or uploaded asset URI.Supported:

https://...
data:image/<format>;base64,...
asset://<ASSET_ID>

string

필수

Image role.Allowed values:

first_frame
last_frame
reference_image

Maximum 1 first_frame
Maximum 1 last_frame
Maximum 9 reference_image
Frame mode and reference mode cannot be mixed
seedance-2-mini also supports first_frame, last_frame, and reference_image

array

Video list with roles.Only reference_video is currently supported in multimodal reference mode.

표시 Field details

string

필수

Video URL or uploaded asset URI.

string

필수

Fixed to:

reference_video

Limits:

seedance-2-mini: up to 3 reference videos

array

Audio list with roles.Only reference_audio is currently supported in multimodal reference mode.

표시 Field details

string

필수

Audio URL, Base64 data, or uploaded asset URI.

string

필수

Fixed to:

reference_audio

Limits:

seedance-2-mini: up to 3 reference audios

audio_with_roles cannot be used alone. At least one visual input is required.

string

기본값:"720p"

Video resolution.Options:

seedance-2: 480p, 720p, 1080p, 4k
seedance-2-fast: 480p, 720p
seedance-2-mini: 480p, 720p

boolean

기본값:true

Whether to generate synced audio.seedance-2-mini also supports this field.

boolean

기본값:false

생성된 동영상의 마지막 프레임 이미지를 반환할지 여부입니다.true로 설정하면 완료된 작업 응답의 result.data[0].last_frame_url에서 이미지 URL을 확인할 수 있습니다.

array

모델이 호출할 수 있는 도구입니다. Seedance 2 시리즈는 현재 웹 검색을 지원합니다.

[{ "type": "web_search" }]

실제 검색 횟수는 usage.tool_usage.web_search에 반환되며, 0은 검색을 실행하지 않았음을 의미합니다.

tools는 텍스트-투-비디오 요청에서만 지원되며 이미지, 동영상 또는 오디오 입력과 함께 사용할 수 없습니다.

integer

Random seed for generation control.

string

ToAPIs 표준 완료 callback입니다. Token URL과 secret을 먼저 설정하며 같은 origin만 덮어쓸 수 있습니다. Webhook.

string

호출자 추적 필드이며 Webhook 설정과 무관합니다.

Use Uploaded Assets

If you already uploaded private assets and obtained a usable asset_id, you do not need to send the original media URL again. Use:

asset://<ASSET_ID>

Asset inputs can be used as:

Images: first_frame, last_frame, reference_image
Videos: reference_video
Audios: reference_audio

Before use, make sure the asset has reached active status. Related guides:

Input Combinations

Typical supported combinations:

Text only: text-to-video
Text + first frame: first-frame image-to-video
Text + first frame + last frame: first-last-frame generation
Text + reference images: multimodal reference generation
Text + reference video: video-reference generation
Text + reference images + reference audio: multimodal reference generation
Text + reference images + reference video + reference audio: multimodal reference generation

seedance-2-mini also supports first-frame and first-last-frame workflows. Use image_with_roles with explicit first_frame / last_frame roles.

seedance-2-mini is currently fixed to 1 output per request and does not expose count / n. Express frame control through image_with_roles using first_frame / last_frame.

응답

string

Task ID for status queries.

string

Your business-side ID. Returned only when client_business_id was provided in the request.

string

Object type, always generation.task.

string

모델 name used for this request.

string

Task status: queued, in_progress, completed, or failed.

integer

Task progress percentage (0-100).

integer

Task creation timestamp.

The submit API returns the base task object. After completion, use Get Video Task 상태 to fetch completed_at, expires_at, and result.type = "video" with result.data[].url and result.data[].format. return_last_frame을 사용하면 result.data[0].last_frame_url, web_search를 사용하면 usage.tool_usage.web_search도 반환됩니다.
