請求範例
這段請求原樣就能執行,沒寫的欄位都用預設值。執行前請先把金鑰放進環境變數 POPNOW_API_KEY。
範例中的 image_url 使用 PopNow 的範例素材,請換成你自己的公開 HTTPS 連結、上傳檔案或已儲存的素材。
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": "vidu/q3/image-to-video",
"input": {
"prompt": "He lands softly on the rooftop, laughs and turns toward the camera while the balloons sway in the evening breeze; slow push-in",
"image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
"resolution": "720p",
"duration_seconds": 5
}
}'回應會立刻帶回 taskId。之後用 GET /api/v1/jobs/recordInfo 取得結果,或在請求裡加上 callBackUrl 等候通知。
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=TASK_ID_FROM_CREATE_TASK" \
-H "Authorization: Bearer $POPNOW_API_KEY"
