统一视频 API
Crazyrouter 提供统一的视频生成接口,支持多种视频模型通过相同的 API 格式调用。Seedance 当前不再推荐走统一 /v1/video/* 协议;请改用原生 /volc/v1/contents/generations/tasks,见 Seedance。支持的模型

|---|---|
veo-3.1-fast | Google Veo 3.1 Fast |
veo-3.1-quality | Google Veo 3.1 Quality |
wan2.2-t2v-plus | Wan 文生视频 |
wan2.5-t2v-preview | Wan 文生视频 |

json={
"model": "veo-3.1-quality",
"prompt": "一只金毛犬在海滩上奔跑,慢动作,电影级画质",
"aspect_ratio": "16:9"
}
)
data = response.json()
task_id = data["task_id"]
print(f"任务 ID: {task_id}")
创建响应
{
"task_id": "video_task_abc123",
"status": "processing"
}
图生视频
在images 参数中传入参考图片:
cURL
curl -X POST https://api.crazyrouter.com/v1/video/create \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{
"model": "wan-ai/wan2.1-i2v-14b-720p",
"prompt": "图片中的人物开始微笑并挥手",
"images": ["https://example.com/portrait.jpg"],
"aspect_ratio": "16:9"
}'
查询任务
GET /v1/video/query?id={task_id}
请求示例
cURL
curl "https://api.crazyrouter.com/v1/video/query?id=video_task_abc123" \
-H "Authorization: Bearer YOUR_API_KEY"
查询响应(处理中)
{
"code": "success",
"message": "",
"data": {
"task_id": "video_task_abc123",
"status": "processing",
"url": ""
}
}
查询响应(已完成)
{
"code": "success",
"message": "",
"data": {
"task_id": "video_task_abc123",
"status": "SUCCESS",
"url": "https://media.crazyrouter.com/task-artifacts/example.mp4",
"artifact_url": "https://media.crazyrouter.com/task-artifacts/example.mp4"
}
}
任务状态
| 状态 | 说明 |
|---|---|
queued | 排队中 |
processing | 处理中 |
SUCCESS | 已完成 |

完整流程示例
Python
import requests
import time
API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.crazyrouter.com"
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {API_KEY}"
}
# 1. 创建视频任务
resp = requests.post(f"{BASE_URL}/v1/video/create", headers=headers, json={
"model": "veo-3.1-quality",
"prompt": "一只金毛犬在海滩上奔跑,慢动作",
"aspect_ratio": "16:9"
})
task_id = resp.json()["task_id"]
print(f"任务已创建: {task_id}")
# 2. 轮询查询状态
while True:
resp = requests.get(f"{BASE_URL}/v1/video/query?id={task_id}", headers=headers)
result = resp.json().get("data", resp.json())
status = result["status"]
print(f"状态: {status}")
if status == "SUCCESS":
print(f"视频地址: {result.get('artifact_url') or result.get('url')}")
break
elif status == "failed":
print("视频生成失败")
break
time.sleep(10)
视频生成通常需要 1-5 分钟,建议轮询间隔为 10 秒。
