Header Parameters

Section titled “Header Parameters”
x-tansr-ts
string
/^\d{1,15}$/

签名时间戳(unix 秒,十进制串;T-A34):与服务器时钟偏差 >300s → 401 signature_invalid

x-tansr-nonce
string
>= 16 characters <= 128 characters

签名随机数(≥16 字符;T-A34):同 keyId 600s 窗内重现 → 401 nonce_replayed

x-tansr-sign
string
/^[0-9a-f]{64}$/

请求签名(hex 小写;T-A34):HMAC-SHA256(K=sha256(SK 明文) 原始摘要, TWP1-HMAC-SHA256\n{METHOD}\n{path+query}\n{ts}\n{nonce}\n{sha256hex(rawBody)});三头须同现,在场恒校验;app signRequired 或 TANSR_API_TWP_REQUIRE_SIGNATURE=1 时未签名恒 401 signature_invalid

Request Bodyrequired

Section titled “Request Bodyrequired”
Media typeapplication/json
object
model

视频模型引用名(候选池三级收敛产物;池外/越权恒 403 model_not_authorized,不泄露池存在性)。缺席 = 授权集顺位第一(与 bundle platformModels.videoGen 首行恒同);空授权集恒 videogen_not_configured

string
>= 1 characters <= 128 characters
prompt
required

正向提示词(平台恒不落日志不落库;wire 帽 10000 = wan3.0 档,上游按模型限长再截)

string
>= 1 characters <= 10000 characters
negativePrompt

反向提示词(dashscope 系上限 500 字符,超限上游自截)

string
>= 1 characters <= 500 characters
duration

视频时长(秒;缺省 5 = 上游缺省档)。费用 = 每秒单价 × 时长,预扣按此上界;wire 帽 30 = wan3.0 档,超模型帽静默钳

integer
>= 2 <= 30
ratio

宽高比(如 16:9/9:16/1:1;wan3.0 另支持 adaptive;缺省随模型;合法域随模型,越域由上游 400 如实回)

string
/^(adaptive|\d{1,2}:\d{1,2})$/
seed

随机种子(内容相对稳定;缺省上游随机)

integer
<= 2147483647
imageUrls

输入图像(i2v 首帧;seedance 支持首帧+尾帧两张;公网 URL 或 data:image/*;base64 URI)。受理与形态域随模型,不受理的模型在场即 400

Array<string>
>= 1 items <= 2 items
audioUrl

参考音频公网 URL(wan2.5/2.6 i2v 可选;超视频时长截断)。不受理的模型在场即 400

string
>= 1 characters <= 2048 characters
