Overview

Decart provides state-of-the-art AI models for transforming videos and images — both in realtime and as batch jobs — through a simple API.

New: Lucy 2 Realtime — Transform yourself into any character live on camera. Upload a reference image and see your movements mapped onto that character. Learn more →

Choose your path

Use this to pick the right API before you integrate:

You want to…	API	Typical method	Best for
Transform live camera/video in an interactive app	Realtime API	`client.realtime.connect()`	Video chat effects, mobile apps, live experiences
Generate or edit videos asynchronously	Queue API	`client.queue.submitAndPoll()`	Content pipelines, long-form jobs, backend automation
Generate or edit images synchronously	Process API	`client.process()`	Image tools, thumbnails, instant edits

If you’re unsure, start with Quickstart. It includes both realtime and batch paths.

Transform yourself into a character with a live camera stream:

import { createDecartClient, models } from "@decartai/sdk";

const model = models.realtime("lucy_2_rt");
const stream = await navigator.mediaDevices.getUserMedia({
  video: { frameRate: model.fps, width: model.width, height: model.height },
});

const client = createDecartClient({ apiKey: "your-api-key-here" });

const realtimeClient = await client.realtime.connect(stream, {
  model,
  onRemoteStream: (s) => {
    document.getElementById("output").srcObject = s;
  },
});

// Upload a reference image and transform
await realtimeClient.set({
  prompt: "Transform into this character",
  image: characterImage,
  enhance: true,
});

Apply artistic styles to a live camera stream:

import { createDecartClient, models } from "@decartai/sdk";

const model = models.realtime("mirage_v2");
const stream = await navigator.mediaDevices.getUserMedia({
  video: { frameRate: model.fps, width: model.width, height: model.height },
});

const client = createDecartClient({ apiKey: "your-api-key-here" });

const realtimeClient = await client.realtime.connect(stream, {
  model,
  onRemoteStream: (s) => {
    document.getElementById("output").srcObject = s;
  },
  initialState: {
    prompt: { text: "Studio Ghibli animation", enhance: true },
  },
});

// Switch styles on the fly
realtimeClient.setPrompt("Cyberpunk city with neon lights");

Transform a video file with a single API call:

import { createDecartClient, models } from "@decartai/sdk";
import { readFileSync, writeFileSync } from "fs";

const client = createDecartClient({ apiKey: process.env.DECART_API_KEY });
const source = new Blob([readFileSync("input.mp4")], { type: "video/mp4" });

const result = await client.queue.submitAndPoll({
  model: models.video("lucy-pro-v2v"),
  data: source,
  prompt: "Transform into anime style",
  onStatusChange: (job) => console.log(job.status),
});

if (result.status === "completed") {
  const buffer = Buffer.from(await result.data.arrayBuffer());
  writeFileSync("output.mp4", buffer);
}
