Pass images, videos, and audio by URL

Pass images, videos and audio to the Genflo API as public HTTP(S) URLs. Multipart uploads, local file paths and Base64 data URLs are not accepted.

File in the model catalog describes media content. On the JSON wire it is a URL string; File[] is an array of URL strings. The generation endpoint does not accept multipart form data or browser File objects.

Send media as URL strings

{
  "images": ["https://cdn.example.com/reference-image.jpg"],
  "videos": ["https://cdn.example.com/reference-video.mp4"],
  "audios": ["https://cdn.example.com/reference-audio.mp3"],
  "first_frame": "https://cdn.example.com/first-frame.jpg",
  "last_frame": "https://cdn.example.com/last-frame.jpg"
}

Each model page lists which of these fields the model accepts, with the formats, item counts and size limits for each one.

Use URLs the gateway can fetch

The gateway forwards ordinary model media as Tencent VOD URL inputs. Seedance media is first registered as account-scoped Tencent AIGC material, then the resulting internal asset reference is used for generation.
