Agnes Videogen

Agnes Video Generation

Generate videos using the Agnes Video V2.0 API.

Prerequisites

• An Agnes AI API key from API Platform
• Base URL: https://apihub.agnes-ai.com/v1

API Architecture

Agnes Video V2.0 uses an asynchronous two-step workflow:

1. Create Video Task — submit the request, get a video_id
2. Retrieve Video Result — poll the video_id to get the final video

API Endpoints

Step 1: Create Video Task

Endpoint: POST https://apihub.agnes-ai.com/v1/videos

Headers:

• Authorization: Bearer YOUR_API_KEY
• Content-Type: application/json

Step 2: Retrieve Video Result

Endpoint: GET https://apihub.agnes-ai.com/agnesapi?video_id=<VIDEO_ID>

Headers:

• Authorization: Bearer YOUR_API_KEY

Optional parameter: model_name — specify model explicitly (e.g., agnes-video-v2.0)

Legacy method (compatibility): GET https://apihub.agnes-ai.com/v1/videos/<TASK_ID>

Model Name

agnes-video-v2.0

Request Parameters (Create Task)

Workflows

      ]
    },

    "frame_rate": 24
  }'

4. Keyframe Interpolation

curl -X POST https://apihub.agnes-ai.com/v1/videos \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \

    "model": "agnes-video-v2.0",
    "prompt": "Generate a smooth cinematic transition between the keyframes, maintaining visual consistency and natural camera movement",
    "extra_body": {
      "image": [
        "https://example.com/keyframe1.png",
        "https://example.com/keyframe2.png"
      ],
      "mode": "keyframes"
    },
    "num_frames": 121,
    "frame_rate": 24
  }'

Retrieve Video Result

Poll until status is "completed" and progress is 100:

curl --location --request GET \
  'https://apihub.agnes-ai.com/agnesapi?video_id=video_xxxxxx' \
  --header 'Authorization: Bearer YOUR_API_KEY'

Completed response:

{
  "id": "task_YOUR_TASK_ID",
