参数

字段类型默认值取值范围作用
prompt必填string—最多 5000 个字符Describe the subject, composition, lighting, and any wording to render. There is no negative prompt: write what to leave out directly in the prompt.
aspect_ratio可选string1:11:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9, 9:21, 2:1, 1:2, 3:1, 1:3, 5:4, … (+1)Output aspect ratio.
resolution可选string2k1k, 1.5k, 2kOutput resolution tier. Every tier costs the same.
num_outputs可选integer11 到 6How many images to generate in one request (1 to 6). Billed per image returned.
enable_prompt_expansion可选booleanfalse—Let the service rewrite and expand the prompt before generating. Off by default so the prompt is followed word for word.
enable_thinking可选booleantrue—Spend extra reasoning on the rewrite for better images, at the cost of a longer wait. Only works while prompt expansion is on.
prompt_optimization_mode可选stringdirectdirect, agentHow prompt expansion rewrites the brief: direct is a single pass that suits most prompts; agent is a multi-step rewrite with finer detail.
seed可选integer—0 到 2147483647Random seed for controlled comparisons.

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/qwen-image-2.1-pro/text-to-image",
  "input": {
    "prompt": "A cozy reading nook beside a rain-streaked window, warm lamp light, a sleeping orange cat on a knitted blanket, soft film grain",
    "num_outputs": 1
  }
}'

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" \
  -H "Authorization: Bearer $POPNOW_API_KEY"
