Quickstart

Start with uploading an image

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:

{
  "id": "fqadqq42xq",
  "name": "test.jpg",
  "content_type": "image/jpeg",
  "size": 185093,
  "etag": "\"14e9a51deaac6bee2dd8b5c52d7d0b5f\"",
  "checksums": {

    "get": "https://api.pruna.ai/v1/files/fqadqq42xq"
  }
}

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.
