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:

# Submit job and poll for completion
JOB_ID=$(curl -s -X POST https://api.decart.ai/v1/jobs/lucy-pro-v2v \
  -H "X-API-KEY: $DECART_API_KEY" \
  -F "data=@input.mp4" \
  -F "prompt=Transform into anime style" | jq -r '.job_id')

while [ "$(curl -s -H "X-API-KEY: $DECART_API_KEY" \
  https://api.decart.ai/v1/jobs/$JOB_ID | jq -r '.status')" != "completed" ]; do sleep 2; done

curl -H "X-API-KEY: $DECART_API_KEY" \
  https://api.decart.ai/v1/jobs/$JOB_ID/content --output output.mp4
