视频生成 API：免费 AI 视频 / 图片生成接口

# 步骤 1 — 提交视频任务
import requests, time

API_KEY = "your_api_key"   # 在 platform.agnes-ai.com 免费获取
BASE = "https://apihub.agnes-ai.com"

headers = {"Authorization": f"Bearer {API_KEY}"}
resp = requests.post(f"{BASE}/v1/videos", headers=headers, json={
    "model": "agnes-video-v2.0",
    "prompt": "一只白狐漫步在薄雾中的竹林",
    "width": 1152, "height": 768,   # 16:9
    "num_frames": 121,               # 约 5 秒 @24fps
    "frame_rate": 24,
})
resp.raise_for_status()
video_id = resp.json().get("video_id") or resp.json().get("task_id")

# 步骤二 — 轮询状态直到完成
while True:
    r = requests.get(f"{BASE}/agnesapi", headers=headers,
                     params={"video_id": video_id}).json()

    if r["status"] == "failed":
        raise RuntimeError(r.get("error", "生成失败"))
    time.sleep(30)
