SDK API Advanced Usage Pricing

Install the SDK

The SDK targets Node 20+ and ships with TypeScript types.

npm

npm install @picsart/ai-sdk

Authenticate

Create a client once with your API key — it's sent as a bearer token on every request.

TypeScript

import { createClient } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY, // sent as: Authorization: Bearer <key>
  apiUrl: 'https://api.green-salad-4efd.toolsminati.workers.dev',
});

Run the model

Call the model with its parameters. This example uses the required ones.

TypeScript

import { createClient } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY,
  apiUrl: 'https://api.green-salad-4efd.toolsminati.workers.dev',
});

const result = await ai.generate('ltx-v2.5-pro', {
  prompt: "A serene mountain lake at golden hour, ultra detailed",
  duration: 6,
  resolution: "1080p",
  aspectRatio: "16:9"
});

console.log(result.url); // video URL
