1. 快速開始

使用 RunComfy 的 API 執行 minimax/minimax-h3/reference-to-video。 可接受的輸入與輸出請參閱模型的 資料結構說明。

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/minimax/minimax-h3/reference-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "The woman from the reference steps out of the shadowed doorway into the low sun, dust lifting around her boots as she scans the street ahead. The camera tracks with her at shoulder height, warm light rakes across her face, and the background falls away into haze. Cinematic pacing, natural movement, anamorphic look.",
    "reference_images": [
      "https://playgrounds-storage-public.runcomfy.net/tools/7394/media-files/ref-promo.webp"
    ],
    "aspect_ratio": "16:9",
    "duration": 5,
    "resolution": "2k"
  }'

2. 身分驗證

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。

3. API 參考

提交請求

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。

curl --request POST \
  --url https://model-api.runcomfy.net/v1/models/minimax/minimax-h3/reference-to-video \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer <token>" \
  --data '{
    "prompt": "The woman from the reference steps out of the shadowed doorway into the low sun, dust lifting around her boots as she scans the street ahead. The camera tracks with her at shoulder height, warm light rakes across her face, and the background falls away into haze. Cinematic pacing, natural movement, anamorphic look.",
    "reference_images": [
      "https://playgrounds-storage-public.runcomfy.net/tools/7394/media-files/ref-promo.webp"
    ],
    "aspect_ratio": "16:9",
    "duration": 5,
    "resolution": "2k"
  }'

查詢請求狀態

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>"

取得請求結果

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>"

取消請求

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 \
  --url https://model-api.runcomfy.net/v1/requests/{request_id}/cancel \
  --header "Authorization: Bearer <token>"

4. 檔案輸入

託管檔案(URL)

請提供可公開存取的 HTTPS 位址。確保目標主機允許伺服器端抓取(無需登入或 Cookie)、未被限流或阻擋機器人。建議:圖片 ≤ 50 MB(約 4K),影片 ≤ 100 MB(約 720p 下 2–5 分鐘)。私人資產請使用穩定或預先簽署 URL。
