​
Overview

Single GIF face swap replaces the primary face in a GIF with a new face image. This endpoint does not require face detection first; submit the original GIF URL and the new face image URL directly.
Multi-face swap still requires a detection step and a detect_id.

​
Request Example

{
  "model": "gif-face-swap",
  "callback_url": "https://your-domain.com/api/callback",
  "input": {
    "video_url": "https://example.com/target.gif",
    "new_face": "https://example.com/new-face.jpg"
  }
}

​
Parameters

​
video_url
string
required
URL of the target GIF where the face will be replaced.
​
new_face
string
required
URL of the new face image.
GIF face swap uses the same request shape as video face swap. Use a GIF URL in video_url and set model to gif-face-swap.

​
Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

For production use, we recommend using callback_url to receive automatic notifications when the task completes, rather than polling the status endpoint.
