Seedance 2.0 Fast

能力

• 通过当前公开任务端点生成视频
• 实时 Schema 提供时支持图片、参考素材、时长或分辨率控制
• 当前参数包括 prompt, resolution, duration

限制

• 模型能力与参数范围可能更新，生产环境应锁定并验证使用的参数组合
• 未出现在实时 Request Schema 中的参数不应假定可用
• 异步任务需要处理轮询、失败、超时和内容安全状态

典型场景

• 产品原型和自动化内容工作流
• 批量媒体生成与程序化创作
• 需要统一鉴权、计费和调用记录的多模型应用

价格与计费示例

• Input tokens | 5.44117647 | 1M tokens
• Output tokens | 5.44117647 | 1M tokens

API 调用示例

cURL

curl -X POST 'https://api.uniall.ai/v1/videos' \
  -H 'Authorization: Bearer $UNIALL_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"aspect_ratio":"16:9","duration":5,"generate_audio":false,"model":"seedance2.0-fast","prompt":"Describe the output you want","resolution":"720p","return_last_frame":false,"watermark":false}'

Python

import json
import requests

payload = json.loads(r'''{"aspect_ratio":"16:9","duration":5,"generate_audio":false,"model":"seedance2.0-fast","prompt":"Describe the output you want","resolution":"720p","return_last_frame":false,"watermark":false}''')
response = requests.post(
    "https://api.uniall.ai/v1/videos",
    headers={"Authorization": "Bearer " + UNIALL_API_KEY},
    json=payload,
)
response.raise_for_status()
result = response.json()

JavaScript

const response = await fetch("https://api.uniall.ai/v1/videos", {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.UNIALL_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({"aspect_ratio":"16:9","duration":5,"generate_audio":false,"model":"seedance2.0-fast","prompt":"Describe the output you want","resolution":"720p","return_last_frame":false,"watermark":false}),
});

if (!response.ok) throw new Error(`HTTP ${response.status}`);
const result = await response.json();
