视频

使用异步任务模型生成视频剪辑 - 提交提示、轮询状态、获取结果。

视频生成在后台运行 - 没有流渲染。流程始终是：创建任务 → 轮询状态 → 下载 MP4。任务将在 24 小时后过期。

1. 创建任务

提交作业并返回任务 ID。根据所选模型的持续时间 × 每秒价格预先扣除成本。

视频模型

…· live

Parameter	Type	Required	Description
model	string	Required	Video model ID. Use /v1/models and filter by output_modalities.includes("video").
prompt	string	Required	Scene description.
mode	string	Optional	"text" (default), "image" (animate a first-frame image), "reference" (style transfer from one or more frames).
duration_seconds	integer	Optional	Clip length. Range depends on the model — typically 5, 8 or 10 s. Defaults to the model's minimum.
aspect_ratio	string	Optional	"16:9", "9:16", "1:1", "4:3" — must be in the model's supported list.
quality	string	Optional	"480p", "720p", "1080p" — must be in the model's supported list.
input_images	array	Optional	[{ url? } \| { b64_json? }] — required for "image" and "reference" modes.
seed	integer	Optional	Reproducibility seed where supported.
sound	boolean	Optional	Enable native audio track on models that produce sound (e.g. wan).

示例

文字转视频

curl https://api.airforce/v1/video/generations \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "wan-2.6",
    "prompt": "A red fox darting across snowy hills at dawn",
    "duration_seconds": 8,
    "aspect_ratio": "16:9",
    "quality": "720p",
    "sound": true
  }'

图像到视频（第一帧）

curl https://api.airforce/v1/video/generations \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kling-1",
    "mode": "image",
    "prompt": "Camera pulls back as the dragon takes off",
    "duration_seconds": 5,
    "aspect_ratio": "16:9",
    "input_images": [{"url": "https://example.com/dragon.jpg"}]
  }'

Parameter	Type	Required	Description
task_id	string	Optional	Persistent task identifier. Use it on every follow-up endpoint.
status	string	Optional	"queued" right after creation.
model	string	Optional	Echo of requested model.
created	integer	Optional	Unix timestamp.
expires_at	integer	Optional	Unix timestamp after which the result is purged (typically created + 86400).
cost_cents	number	Optional	Up-front cost debited from your balance. Refunded if the task ultimately fails.

{
  "task_id": "vid_01HXY1234ABCD",
  "status": "queued",
  "model": "wan-2.6",
  "created": 1715000000,
  "expires_at": 1715086400,
  "cost_cents": 320
}

2. 轮询状态

每 5-15 秒轮询一次。任务通常在 30 秒至 4 分钟内完成，具体取决于持续时间和模型。当状态翻转为“已完成”时，同一端点返回结果 URL。

GEThttps://api.airforce/v1/video/tasks/:task_id

Parameter	Type	Required	Description
status	string	Optional	"queued" \| "running" \| "completed" \| "failed" \| "expired".
progress	integer	Optional	0–100 while running. Absent for queued tasks.
result_url	string	Optional	MP4 download URL once status is "completed". Pre-signed; valid until expires_at.
thumbnail_url	string	Optional	Optional poster frame.
error	object	Optional	Set when status is "failed". { type, message }.
cost_cents	number	Optional	Final cost. Equals the create-time cost on success.

{
  "task_id": "vid_01HXY1234ABCD",
  "status": "completed",
  "progress": 100,
  "result_url": "https://cdn.api.airforce/video/vid_01HXY1234ABCD.mp4",
  "thumbnail_url": "https://cdn.api.airforce/video/vid_01HXY1234ABCD.jpg",
  "model": "wan-2.6",
  "duration_seconds": 8,
  "expires_at": 1715086400,
  "cost_cents": 320
}

2b.串流进度（可选）

使用服务器发送事件流跳过轮询循环。每次进度更改都会发出一个事件，并在任务处于最终状态时关闭。与 GET 端点相同的有效负载形状。

GEThttps://api.airforce/v1/video/tasks/:task_id/stream

event: progress
data: {"task_id":"vid_01HXY...","status":"running","progress":12}

event: progress
data: {"task_id":"vid_01HXY...","status":"running","progress":58}

event: completed
data: {"task_id":"vid_01HXY...","status":"completed","progress":100,"result_url":"https://cdn.api.airforce/video/vid_01HXY....mp4"}

3. 列出并删除

GEThttps://api.airforce/v1/video/tasks

返回您最近的任务（最新的在前）。对于仪表板呈现历史视图很有用。

Parameter	Type	Required	Description
limit	integer	Optional	Max items returned. Default 50, max 200. Pass as a query string.
status	string	Optional	Filter to one status, e.g. ?status=running.

curl "https://api.airforce/v1/video/tasks?limit=20&status=completed" \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY"

DELETEhttps://api.airforce/v1/video/tasks/:task_id

从您的历史记录中删除该任务。 MP4 也会从 CDN 存储中删除。不予退款——费用已被扣除。

成本和限制

每个视频模型都会公开您可以读取的功能元数据 /v1/models:

Parameter	Type	Required	Description
video_caps.aspect_ratios	array	Optional	Allowed aspect_ratio values.
video_caps.qualities	array	Optional	Allowed quality values.
video_caps.min_duration_s / max_duration_s	integer	Optional	Allowed range for duration_seconds.
video_caps.modes	array	Optional	Subset of ["text", "image", "reference"] supported.
video_caps.price_per_second_cents	integer	Optional	Cost = duration_seconds × this value.

Cost is debited at task creation. Failed tasks (status "failed" or "expired") refund the cost.
Max 4 concurrent video tasks per API key.
Result URLs are pre-signed and stop working at expires_at. Download or copy the MP4 to your own storage if you need it longer.

端到端脚本

async function generateVideo(prompt) {
  const create = await fetch('https://api.airforce/v1/video/generations', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'wan-2.6',
      prompt,
      duration_seconds: 8,
      aspect_ratio: '16:9',
      quality: '720p',
    }),
  }).then(r => r.json());

  const { task_id } = create;

  // Poll until done.
  while (true) {
    await new Promise(r => setTimeout(r, 8_000));
    const task = await fetch(
      `https://api.airforce/v1/video/tasks/${task_id}`,
      { headers: { Authorization: `Bearer ${API_KEY}` } },
    ).then(r => r.json());

    if (task.status === 'completed') return task.result_url;
    if (task.status === 'failed' || task.status === 'expired') {
      throw new Error(task.error?.message ?? task.status);
    }
  }
}
