negative_promptstring選填不想出現的東西。
audio_urlstring選填要使用的人聲或音樂。
generate_audioboolean選填影響價格加上和畫面相配的聲音:人聲、環境音和音效。
resolutionstring選填影響價格輸出尺寸。越大越清晰,價格也越高。
duration_secondsinteger選填影響價格影片長度,按秒計費。
shot_typestring選填Single continuous shot, or a multi-shot edit.
enable_prompt_expansionboolean選填讓模型替簡短的提示詞補上細節。
seedinteger選填用同一個數字,結果就能重現。

回應、輪詢與回呼
所有模型的用法都一樣:先建立任務,再輪詢,或等待回呼。
先報價
curl -X POST https://api.popnow.ai/api/v1/jobs/quote \

"duration_seconds": 5,
"shot_type": "single"
}
}'請求內容和 createTask 相同。它回傳預估扣款和最高可能扣款,不會真的執行。
已受理
HTTP/1.1 202 Accepted
{
"code": 200,
"msg": "success",
"data": {
"taskId": "task_01k3m8x9q2z4v7n5p6r8s0t1w3",
"state": "queued"
},
"request_id": "req_example_create"
}HTTP 202 代表任務已受理,點數先凍結、尚未扣除。最終扣款不會超過凍結額。
查詢狀態
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
-H "Authorization: Bearer $POPNOW_API_KEY"每隔幾秒查詢一次並逐步拉長間隔,state 變成 succeeded、failed、canceled 或 expired 時停止。
