Wan 2.1 LoRA API 调用参考

Wan 2.1 生成和编辑视频，可挂你的 LoRA，含运镜

用一个 PopNow API 密钥，就能在自己的代码里调用 Wan 2.1 LoRA。下面列出要填的调用名、这个型号接受的每个输入字段、每次请求花多少积分，以及一段可以直接粘进终端运行的请求。

参数说明直接取自型号的输入 schema，暂时只有英文。

调用名

1 积分 = 0.01 美元。任务受理时先冻结可能的最高费用，完成后按实际用量结算、向上取整到整积分，多冻的退回；失败的任务不扣积分。想在运行前知道确切数字，先调 POST /api/v1/jobs/quote。

参数

字段类型默认值取值范围作用
prompt必填string——Describe the scene, the action and the camera. If a LoRA has trigger words, put them first.
negative_prompt可选string——What must stay out of the clip.
aspect_ratio可选string16:916:9, 9:16Output aspect ratio.
resolution可选string480p480p, 720pOutput resolution.
duration_seconds可选integer55, 10Clip length: 5 or 10 seconds.
loras可选array<object>[]最多 3 项Up to three LoRA weight files trained for Wan 2.1 14B, each with its own strength.
guidance_scale可选number50 到 20How closely the clip follows the prompt, from 0 to 20.
flow_shift可选number—1 到 10Flow-matching timestep shift, from 1 to 10. Leave it out for the default (3 at 480p, 5 at 720p).
steps可选integer301 到 40Denoising steps, from 1 to 40. Fewer steps return faster and softer.
seed可选integer—0 到 2147483647Random seed for controlled comparisons, not a frame-identical guarantee.

请求示例

这段请求原样就能运行，没写的字段都用默认值。运行前先把密钥放进环境变量 POPNOW_API_KEY。

POST /api/v1/jobs/createTask
curl -X POST "https://api.popnow.ai/api/v1/jobs/createTask" \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "model": "alibaba/wan-2.1-lora/text-to-video",
  "input": {
    "prompt": "A paper boat drifts down a rain-soaked street at dusk, neon signs reflecting in the water, slow tracking shot at ground level",
    "duration_seconds": 5,
    "resolution": "480p"
  }
}'

响应里会立刻带回 taskId。之后用 GET /api/v1/jobs/recordInfo 取结果，或者在请求里加上 callBackUrl 等通知。

GET /api/v1/jobs/recordInfo
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=TASK_ID_FROM_CREATE_TASK" \
