Only the crowd's hands show at the bottom of the frame. No signs, no captions, no readable flags. He lifts one hand as fallen leaves cross the steps. A clear speaking voice and distant traffic."
}'將 YOUR_API_TOKEN 環境變數設為您的 API 金鑰（在 個人資料中管理金鑰），並在每個請求的 Authorization 標頭中以 Bearer 權杖形式攜帶： Authorization: Bearer $YOUR_API_TOKEN。
提交非同步生成工作後，將立即取得 request_id 以及用於查詢狀態、取得結果與取消的 URL。

}'依 request_id 取得目前狀態（「in_queue」、「in_progress」、「completed」或「cancelled」）。
curl --request GET \
--url https://model-api.runcomfy.net/v1/requests/{request_id}/status \
--header "Authorization: Bearer <token>"取得指定 request_id 的最終輸出與中繼資料；若工作尚未完成，回應會回傳目前狀態，方便繼續輪詢。
curl --request GET \
--url https://model-api.runcomfy.net/v1/requests/{request_id}/result \
--header "Authorization: Bearer <token>"透過 request_id 取消排隊中的工作；進行中的工作無法取消。
curl --request POST \
