Quick Start

Process Files

import asyncio
import os
from decart import DecartClient, models

async def main():
    async with DecartClient(api_key=os.getenv("DECART_API_KEY")) as client:
        # Generate a video from text
        result = await client.process({
            "model": models.video("lucy-pro-t2v"),
            "prompt": "A cat walking in a lego world",
        })

        # Save the result
        with open("output.mp4", "wb") as f:
            f.write(result)

asyncio.run(main())

Video Transformation

async with DecartClient(api_key=os.getenv("DECART_API_KEY")) as client:
    # Transform a video file
    with open("input.mp4", "rb") as video_file:
        result = await client.process({
            "model": models.video("lucy-pro-v2v"),
            "prompt": "Anime style with vibrant colors",
            "data": video_file,
            "enhance_prompt": True,
        })

    # Save the result
    with open("output.mp4", "wb") as f:
        f.write(result)

# 1. Update version in pyproject.toml
version = "0.0.4"

# 2. Commit and push
git add pyproject.toml
git commit -m "chore: bump version to 0.0.4"
git push

# 3. Create a GitHub release
gh release create v0.0.4 \
  --title "v0.0.4 - Feature summary" \
  --notes "## What's Changed
