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。
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": "xai/grok-tts/text-to-speech",
"input": {
"text": "Hi there! This voice was created with the PopNow API in just a few seconds."
}
}'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"
