How to Provide File Input

There are 3 ways to provide files for the image_url parameter:

Recommended

Image URL

Pass a publicly accessible URL directly. With the Storage API (POST /v1/files/upload-url) the file uploads straight to S3 (50MB per file) and you pass the returned file_url.

{
  "model": "fal-ai/kling-video/v3/turbo/standard/image-to-video",
  "input": {
    "prompt": "your prompt here",
    "image_url": "https://example.com/image.jpg"
  }
}

Direct Upload (Multipart)

Attach files directly to POST /v1/predictions/upload. No separate upload step, but the bytes pass through the API server so the whole request is capped at 10MB.

curl -X POST "https://api.core.today/v1/predictions/upload" \
  -H "X-API-Key: cdt_your_api_key" \
  -F "model=fal-ai/kling-video/v3/turbo/standard/image-to-video" \
  -F 'input={"prompt":"your prompt here"}' \
  -F "file:image_url=@your_file.png"

See the File Upload docs for more upload methods including Presigned URLs.
