curl -X POST "https://api.pruna.ai/v1/files" \
  -H "apikey: YOUR_API_KEY" \
  -F "content=@/path/to/your/file.jpg"

Note: Use -F (form) with @ prefix to upload a file from your local filesystem. The file path should be absolute or relative to your current directory.

Response:

  }
}

Then pass that image in the "image" field

curl -X POST 'https://api.pruna.ai/v1/predictions' \
  -H 'Content-Type: application/json' \
  -H 'apikey: YOUR_API_KEY' \
  -H 'Model: wan-i2v' \
  -d '{
    "input": {
      "image": "https://your-image-url.com/photo.jpg",
      "prompt": "The camera slowly pushes in, the person turns their head and smiles, gentle wind moves their hair",
      "num_frames": 81,
      "resolution": "720p",
      "frames_per_second": 16
    }
  }'

Note: The image parameter should be a publicly accessible URL. You can upload files using the /v1/files endpoint first.
